MIC29150/29300/29500/29750
High-Current Low-Dropout Regulators
General Description
The MIC29150/29300/29500/29750 are high current, high accuracy, low-dropout voltage regulators. Using Micrel's proprietary Super eta PNP(R) process with a PNP pass element, these regulators feature 350mV to 425mV (full load) typical dropout voltages and very low ground current. Designed for high current loads, these devices also find applications in lower current, extremely low dropout-critical systems, where their tiny dropout voltage and ground current values are important attributes. The MIC29150/29300/29500/29750 are fully protected against overcurrent faults, reversed input polarity, reversed lead insertion, overtemperature operation, and positive and negative transient voltage spikes. Five pin fixed voltage versions feature logic level ON/OFF control and an error flag which signals whenever the output falls out of regulation. Flagged states include low input voltage (dropout), output current limit, overtemperature shutdown, and extremely high voltage spikes on the input. On the MIC29xx1 and MIC29xx2, the ENABLE pin may be tied to VIN if it is not required for ON/OFF control. The MIC29150/29300/29500 are available in 3-pin and 5-pin TO-220 and surface mount TO-263 (D2Pak) packages. The MIC29750 7.5A regulators are available in 3-pin and 5-pin TO-247 packages. The 1.5A, adjustable output MIC29152 is available in a 5-pin power D-Pak (TO-252) package. For applications with input voltage 6V or below, see MIC37xxx LDOs.

MIC29150/29300/29500/29750
Maximum positive supply voltage of 60V must be of limited duration (<100msec) and duty cycle (1%). The maximum continuous supply voltage is 26V. Exceeding the absolute maximum rating may damage the device. The device is not guaranteed to function outside its operating rating. Devices are ESD sensitive. Handling precautions recommended. Specification for packaged product only. Full load current (IFL) is defined as 1.5A for the MIC29150, 3A for the MIC29300, 5A for the MIC29500, and 7.5A for the MIC29750 families. Dropout voltage is defined as the input-to-output differential when the output voltage drops to 99% of its normal value with VOUT + 1V applied to VIN. VIN = VOUT (nominal) + 1V. For example, use VIN = 4.3V for a 3.3V regulator or use 6V for a 5V regulator. Employ pulse-testing procedures to pin current. Ground pin current is the regulator quiescent current. The total current drawn from the source is the sum of the load current plus the ground pin current. Output voltage temperature coefficient is defined as the worst case voltage change divided by the total temperature range.
10. 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 a200mA load pulse at VIN = 20V (a 4W pulse) for T = 10ms. 11. Comparator thresholds are expressed in terms of a voltage differential at the Adjust terminal below the nominal reference voltage measured at 6V input. To express these thresholds in terms of output voltage change, multiply by the error amplifier gain = VOUT/VREF = (R1 + R2)/R2. For example, at a programmed output voltage of 5V, the Error output is guaranteed to go low when the output drops by 95mV x 5V/1.240V = 384mV. Thresholds remain constant as a percent of VOUT as VOUT is varied, with the dropout warning occurring at typically 5% below nominal, 7.7% guaranteed. 12. VEN 0.8V and VIN 26V, VOUT = 0. 13. When used in dual supply systems where the regulator load is returned to a negative supply, the output voltage must be diode clamped to ground.

MIC29150/29300/29500/29750 * Output Current, IOUT * Output Voltage, VOUT * Input Voltage, VIN First, we calculate the power dissipation of the regulator from these numbers and the device parameters from this datasheet.
Application Information
The MIC29150/29300/29500/29750 are high performance low-dropout voltage regulators suitable for all moderate to high-current voltage regulator applications. Their 350mV to 425mV typical dropout voltage at full load make them especially valuable in battery powered systems and as high efficiency noise filters in "post-regulator" applications. Unlike older NPNpass transistor designs, where the minimum dropout voltage is limited by the base-emitter voltage drop and collector-emitter saturation voltage, dropout performance of the PNP output of these devices is limited merely by the low VCE saturation voltage. A trade-off for the low-dropout voltage is a varying base driver requirement. But Micrel's Super eta PNP(R) process reduces this drive requirement to merely 1% of the load current. The MIC29150/29300/29500/29750 family of regulators are fully protected from damage due to fault conditions. Current limiting is provided. This limiting is linear; output current under overload conditions is constant. Thermal shutdown disables the device when the die temperature exceeds the 125C maximum safe operating temperature. Transient protection allows device (and load) survival even when the input voltage spikes between -20V and +60V. When the input voltage exceeds about 35V to 40V, the over voltage sensor temporarily disables the regulator. The output structure of these regulators allows voltages in excess of the desired output voltage to be applied without reverse current flow. MIC29xx1 and MIC29xx2 versions offer a logic level ON/OFF control: when disabled, the devices draw nearly zero current. An additional feature of this regulator family is a common pinout: a design's current requirement may change up or down yet use the same board layout, as all of these regulators have identical pinouts.
MIC29XXX
VIN IN OUT VOUT
PD = IOUT (1.01 VIN - VOUT ) Where the ground current is approximated by 1% of IOUT. Then the heat sink thermal resistance is determined with this formula: T - TA SA = JMAX - (JC + CS ) PD
GND
Where TJMAX 125C and CS is between 0 and 2C/W. The heat sink may be significantly reduced in applications where the minimum input voltage is known and is large compared with the dropout voltage. Use a series input resistor to drop excessive voltage and distribute the heat between this resistor and the regulator. The low-dropout properties of Micrel Super eta PNP(R) regulators allow very significant reductions in regulator power dissipation and the associated heat sink without compromising performance. When this technique is employed, a capacitor of at least 0.1F is needed directly between the input and regulator ground. Please refer to Application Note 9 and Application Hint 17 for further details and examples on thermal design and heat sink specification. With no heat sink in the application, calculate the junction temperature to determine the maximum power dissipation that will be allowed before exceeding the maximum junction temperature of the MIC29152. The maximum power allowed can be calculated using the thermal resistance (JA) of the D-Pak adhering to the following criteria for the PCB design: 2 oz. copper and 100mm2 copper area for the MIC29152. For example, given an expected maximum ambient temperature (TA) of 75C with VIN = 3.3V, VOUT = 2.5V, and IOUT = 1.5A, first calculate the expected PD using Equation (1); PD=(3.3V-2.5V)1.5A-(3.3V)(0.016A)=1.1472W Next, calcualte the junction temperature for the expected power dissipation. TJ=(JAxPD)+TA=(56C/Wx1.1472W)+75C=139.24C Now determine the maximum power dissipation allowed that would not exceed the IC's maximum junction temperature (125C) without the useof a heat sink by PD(MAX)=(TJ(MAX)-TA)/JA=(125C-75C)/(56C/W) =0.893W

Micrel, Inc. Capacitor Requirements For stability and minimum output noise, a capacitor on the regulator output is necessary. The value of this capacitor is dependent upon the output current; lower currents allow smaller capacitors. The MIC29150/29300/29500/29750 regulators are stable with the following minimum capacitor values at full load: Device Full Load Capacitor MIC29150...............................................10F MIC29300...............................................10F MIC29500...............................................10F MIC29750...............................................22F This capacitor need not be an expensive low ESR type: aluminum electrolytics are adequate. In fact, extremely low ESR capacitors may contribute to instability. Tantalum capacitors are recommended for systems where fast load transient response is important. Where the regulator is powered from a source with a high AC impedance, a 0.1F capacitor connected between Input and GND is recommended. This capacitor should have good characteristics to above 250kHz. Minimum Load Current The MIC29150-29750 regulators are specified between finite loads. If the output current is too small, leakage currents dominate and the output voltage rises. The following minimum load current swamps any expected leakage current across the operating temperature range: Device Minimum Load MIC29150................................................5mA MIC29300................................................7mA MIC29500..............................................10mA MIC29750..............................................10mA

Figure 4. Adjustable Regulator with Resistors
The adjustable regulator versions, MIC29xx2 and MIC29xx3, allow programming the output voltage anywhere between 1.25V and the 25V. Two resistors are used. The resistor values are calculated by:
V R 1 = R 2 x OUT - 1 1.240
where VOUT is the desired output voltage. Figure 4 shows component definition. Applications with widely varying load currents may scale the resistors to draw the minimum load current required for proper operation (see "Minimum Load Current" section). Error Flag MIC29xx1 and MIC29xx3 versions feature an Error Flag, which looks at the output voltage and signals an error condition when this voltage drops 5% below its expected value. The error flag is an open-collector output that pulls low under fault conditions. It may sink 10mA. Low output voltage signifies a number of possible problems, including an overcurrent fault (the device is in current limit) and low input voltage. The flag output is inoperative during overtemperature shutdown conditions. Enable Input MIC29xx1 and MIC29xx2 versions feature an enable (EN) input that allows ON/OFF control of the device. Special design allows "zero" current drain when the device is disabled--only microamperes of leakage current flows. The EN input has TTL/CMOS compatible thresholds for simple interfacing with logic, or may be directly tied to 30V. Enabling the regulator requires approximately 20A of current.
