The AAT3236 is a MicroPower low dropout (LDO) linearregulator designed to deliver a continuous 300mA outputload current and is capable of handling short durationcurrent peaks up to 500mA. With a very small footprintSOT23-5 package, it is ideally suited for portable applicationswhere low noise, high power supply ripple rejection(PSRR), extended battery life, and small size arecritical. The AAT3236 features fast transient responseand low output self noise for powering sensitive RF circuitry.Other features include low quiescent current,typically 100μA, and low dropout voltage, typically300mV at full output load current. The device has internaloutput short-circuit protection and thermal shutdownto prevent damage under extreme conditions.
