NCP3335A http://onsemi.com 18 applications information reverse bias protection reverse bias is a condition caused when the input voltage goes to zero, but the output voltage is kept high either by a large output capacitor or another source in the application which feeds the output pin. normally in a bipolar ldo all the current will flow from the output pin to input pin through the pn junction with limited current capability and with the potential to destroy the ic. due to an improved architecture, the NCP3335A can withstand up to 7.0 v on the output pin with virtually no current flowing from output pin to input pin, and only negligible amount of current (tens of a) flowing from the output pin to ground for infinite duration. input capacitor an input capacitor of at least 1.0 f, any type, is recommended to improve the transient response of the regulator and/or if the regulator is located more than a few inches from the power source. it will also reduce the circuit?s sensitivity to the input line impedance at high frequencies. the capacitor should be mounted with the shortest possible track length directly across the regular?s input terminals. output capacitor the NCP3335A remains stable with any type of capacitor as long as it fulfills its 1.0 f requirement. there are no constraints on the minimum esr and it will remain stable up to an esr of 5.0 . larger capacitor values will improve the noise rejection and load transient response. noise reduction pin output noise can be greatly reduced by connecting a 10 nf capacitor (c nr ) between the noise reduction pin and ground (see figure 1). in applications where very low noise is not required, the noise reduction pin can be left unconnected. for the adjustable version, in addition to the 10 nf c nr , a 68 pf capacitor connected in parallel with r1 (see figure 2) is recommended to further reduce output noise and improve stability. adjustable operation the output voltage can be set by using a resistor divider as shown in figure 2 with a range of 1.25 to 10 v. the appropriate resistor divider can be found by solving the equation below. the recommended current through the resistor divider is from 10 a to 100 a. this can be accomplished by selecting resistors in the k range. as result, the i adj *r2 becomes negligible in the equation and can be ignored. v out 1.25 * 1 r1 r2 i adj *r2 (eq. 1) example: for v out = 2.9 v, can use r 1 = 36 k and r 2 = 27 k . 1.25 * 1 36 k 27 k 2.91 v (eq. 2) dropout voltage the voltage dropout is measured at 97% of the nominal output voltage. thermal considerations internal thermal limiting circuitry is provided to protect the integrated circuit in the ev ent that the maximum junction temperature is exceed ed. this feature provides protection from a catastrophic device failure due to accidental overheating. this protection feature is not intended to be used as a substitute to heat sinking. the maximum power that can be dissipated, can be calculated with the equation below: p d t j(max) t a r ja (eq. 3) for improved thermal performance, contact the factory for the dfn package option. the dfn package includes an exposed metal pad that is specifically designed to reduce the junction to air thermal resistance, r ja .
