1 / 16 page  AAT3236 300mA CMOS High Performance LDO Typical Application AAT3236 IN EN BYP VIN VOUT GND GND GND OUT ON/OFF 2.2 µF 10nF 1 µF 3236.2001.11.0.9 1 PowerLinear™ General Description The AAT3236 is a MicroPower™ Low Dropout Linear Regulator designed to deliver a continuous 300mA output load current and is capable of han- dling short duration current peaks up to 500mA. With a very small footprint SOT23-5 package it is ideally suited for portable applications where low noise, high power supply ripple rejection, extended battery life and small size are critical. The AAT3236 features fast transient response and low output self noise for powering sensitive RF circuitry. Other fea- tures include low quiescent current, typically 100µA, and low dropout voltage, typically 300mV at full output load current. The device has internal out- put short circuit protection and thermal shutdown to prevent damage under extreme conditions. The AAT3236 also features a low-power shutdown mode for longer battery life. A bypass pin is pro- vided to improve PSRR performance by connect- ing an external capacitor from the AAT3236's refer- ence output to ground. The AAT3236 is available in a space saving SOT23-5 or SC70JW-8 package in 7 factory pro- grammed voltages of 2.5V, 2.7V, 2.8V, 2.85V, 3.0V, 3.3V, or 3.5V.
