Features
* Extremely Low Supply Current for Longer Battery Life * Select ModeTM Operation: Selectable Output Voltages for High Design Flexibility * Very Low Dropout Voltage * 10sec (Typ.) Wake-Up Time from SHDN * Maximum 150mA Output Current per Output * High Output Voltage Accuracy * Power-Saving Shutdown Mode * RESET Output Can Be Used as a Low Battery Detector or Processor Reset Generator * Over Current Protection and Over Temperature Shutdown * Space Saving 8-Pin MSOP Package
General Description
The TC1306 combines two CMOS Low Dropout Regulators and a Microprocessor Monitor in a space saving 8-Pin MSOP package. Designed specifically for battery operated systems, total supply current is typically 120A at full load, 20 to 60 times lower than in bipolar regulators. The TC1306 features selectable output voltages for higher design flexibility. The dual-state SELECT input pin allows the user to select VOUT2 from 2 different values (2.8V and 3.0V). VOUT1 supplies a fixed 1.8V voltage. An active low RESET is asserted when the output voltage VOUT2 falls below the 2.63V reset voltage threshold. The RESET output remains low for 300msec (typical) after VOUT2 rises above reset threshold. When the shutdown control (SHDN1) is low, the regulator output voltage VOUT1 falls to zero and RESET output remains valid. When the shutdown control (SHDN2) is low, the regulator output voltage VOUT2 falls to zero and RESET output is low. Other key features for the device include ultra low noise operation, fast response to step changes in load and very low dropout voltage (typically 125mV at full load). The device also incorporates both over temperature and over current protection. Each regulator is stable with an output capacitor of only 1F and has a maximum output current of 150mA.

The minimum VIN has to meet two conditions: VIN 2.7 and VIN = VR + VDROPOUT. VR is the regulator output voltage setting. For example: VR = 2.8V, 3.0V. TC VOUT = (VOUTMAX - VOUTMIN) x 106 VOUT x T Regulation is measured at a constant junction temperature using low duty cycle pulse testing. Load regulation is tested over a load range from 0.1mA to the maximum specified output current. Changes in output voltage due to heating effects are covered by the thermal regulation specification. Dropout voltage is defined as the input to output differential at which the output voltage drops 2% below its nominal value measured at a 1V differential. Thermal Regulation is defined as the change in output voltage at a time T after a change in power dissipation is applied, excluding load or line regulation effects. Specifications are for a current pulse equal to ILMAX at VIN = 6V for T = 10 msec. The maximum allowable power dissipation is a function of ambient temperature, the maximum allowable junction temperature and the thermal resistance from junction-to-air (i.e., TA, TJ, JA). Exceeding the maximum allowable power dissipation causes the device to initiate thermal shutdown. Please see Section 5.0 Thermal Considerations section of this data sheet for more details.

DETAILED DESCRIPTION
The TC1306 is a precision fixed output voltage regulator that contains two fully independent 150mA outputs. The device also features separate shutdown modes for low-power operation. The Select ModeTM operation allows the user to select VOUT2 from two different values (2.8V, 3.0V), therefore providing high design flexibility. VOUT1 supplies a fixed 1.8V output voltage. The CMOS construction of the TC1306 results in a very low supply current, which does not increase with load changes. In addition, VOUT remains stable and within regulation at no load currents.
The TC1306 also features an integrated microprocessor supervisor that monitors the VOUT2 output. The active low RESET signal is asserted when the voltage of VOUT2 falls below the reset voltage threshold (2.63V). The RESET output remains low for 300msec (typical) after VOUT2 rises above the reset threshold. The RESET output of the TC1306 is optimized to reject fast transient glitches on the monitored output line.

TYPICAL APPLICATIONS
Input and Output Capacitor
4.3
Select ModeTM Operation
The TC1306 is stable with a wide range of capacitor values and types. A capacitor with a minimum value of 1F from VOUT to Ground is required. The output capacitor should have an effective series resistance (ESR) of 0.1 to 10 for a 1F capacitor and 0.01 to 10 for a 10F capacitor. A 1F capacitor should be connected from the VIN to GND if there is more than 10 inches of wire between the regulator and the AC filter capacitor, or if a battery is used as the power source. Aluminum electrolytic or tantalum capacitor types can be used. (Since many aluminum electrolytic capacitors freeze at approximately -30C, solid tantalums are recommended for applications operating below -20C). When operating from sources other than batteries, supply-noise rejection and transient response can be improved by increasing the value of the input and output capacitors and employing passive filtering techniques.
The Select ModeTM operation is a dual-state input that allows the user to select VOUT2 from two different values. By applying a logic low to the SELECT pin, VOUT2 is set to supply a 2.8V output voltage. A logic high signal at the SELECT pin sets VOUT2 to 3.0V. This output voltage functionality provides high design flexibility and minimizes cost associated with inventory, time-to-market and new device qualifications.
4.4
Turn On Response
The turn on response is defined as two separate response categories, Wake Up Time (tWK) and Settling Time (tS). The TC1306 has a fast Wake Up Time (10sec typical) when released from shutdown. See Figure 4-1 for the Wake Up Time designated as tWK. The Wake Up Time is defined as the time it takes for the output to rise to 2% of the VOUT value after being released from shutdown. The total turn on response is defined as the Settling Time (tS), see Figure 4-1. Settling Time (inclusive with tWK) is defined as the condition when the output is within 2% of its fully enabled value (40sec typical) when released from shutdown. The settling time of the output voltage is dependent on load conditions, output voltage and VOUT (RC response).
4.2
Shutdown Mode
Applying a logic high to each of the shutdown pins turns on the corresponding output. Each regulator enters shutdown mode when a logic low is applied to the corresponding input. During shutdown mode, output voltage falls to zero, and regulator supply current is reduced to 0.5A (max). If shutdown mode is not necessary, the pins should be connected to VIN.

THERMAL CONSIDERATIONS
Thermal Shutdown
Equation 5-1 can be used in conjunction with Equation 5-2 to ensure regulator thermal operation is within limits. For example: Given: VINMAX = 3.8V 5% VOUT1MIN = 1.8V 2.5% VOUT2MIN = 3.0V 2.5% ILOAD1MAX = 60mA ILOAD2MAX = 120mA TJMAX TAMAX JA = 125C = 55C = 200C/W
Integrated thermal protection circuitry shuts the regulator off when die exceeds approximately 160C. The regulator remains off until the die temperature drops to approximately 145C. Thermal shutdown is intended to protect the device under transient accidental (fault) overload conditions. Thermal Shutdown may not protect the LDO while operating above junction temperatures of 125C continuously. Sufficient thermal evaluation of the design needs to be conducted to ensure that the junction temperature does not exceed 125C.
5.2
Power Dissipation
Find: 1. Actual power dissipation 2. Maximum allowable dissipation Actual power dissipation: PD [(VINMAX - VOUT1MIN)] x ILOAD1MAX + [(VINMAX - VOUT2MIN)] x ILOAD2MAX [(3.8 x 1.05) - (1.8 x .975)] x 60 x 10-3 + [(3.8 x 1.05) - (3.0 x .975)] x 120 x 10-3 = 256mW Maximum allowable power dissipation: PD = (TJMAX - TAMAX) JA = (125 - 55) 200 = 350mW In this example, the TC1306 dissipates a maximum of 262mW; below the allowable limit of 350mW. In a similar manner, Equation 5-1 and Equation 5-2 can be used to calculate maximum current and/or input voltage limits. For example, the maximum allowable VIN is found by substituting the maximum allowable power dissipation of 350mW into Equation 5-1, from which VINMAX = 4.5V.
The amount of power the regulator dissipates is primarily a function of input and output voltage, and output current. The following equation is used to calculate worst case actual power dissipation.
EQUATION 5-1:
PD (VINMAX - VOUT1MIN)ILOAD1MAX + (VINMAX - VOUT2MIN)ILOAD2MAX Where: PD = Worst case actual power dissipation VINMAX = Maximum voltage on VIN VOUT1MIN = Minimum regulator output voltage1 ILOAD1MAX = Maximum output (load) current1 VOUT2MIN = Minimum regulator output voltage2 ILOAD2MAX = Maximum output (load) current2 The maximum allowable power dissipation (Equation 5-2) is a function of the maximum ambient temperature (TAMAX), the maximum allowable die temperature (125C), and the thermal resistance from junction-to-air (JA). The MSOP-8 package has a JA of approximately 200C/W when mounted on a four layer FR4 dielectric copper clad PC board.
5.3
Layout Considerations
EQUATION 5-2:
PDMAX = (TJMAX - TAMAX) JA Where all terms are previously defined.
The primary path of heat conduction out of the package is via the package leads. Therefore, layouts having a ground plane, wide traces at the pads, and wide power supply bus lines combine to lower JA and therefore increase the maximum allowable power dissipation limit.

Note the following details of the code protection feature on Microchip devices: * * * Microchip products meet the specification contained in their particular Microchip Data Sheet. Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the intended manner and under normal conditions. There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip's Data Sheets. Most likely, the person doing so is engaged in theft of intellectual property. Microchip is willing to work with the customer who is concerned about the integrity of their code. Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not mean that we are guaranteeing the product as "unbreakable."

Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our products. Attempts to break Microchip's code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.
