General Description(AAT3216IGV-2.8-T1 Datasheet and PDF download)
The AAT3216 MicroPower(TM) Low Dropout Linear Regulator is ideally suited for portable applications
where low noise, extended battery life and small size are critical. The AAT3216 has been specifi-
cally designed for low output noise performance,fast transient response and high power supply
rejection ratio (PSRR), making it ideal for powering sensitive RF circuits. Other features include low quiescent current, typically 70μA, and low dropout voltage which is typically less than 200mV at full output current. The device is output short circuit protected and has a thermal shutdown circuit for additional protection under extreme conditions.The AAT3216 also features a low-power shutdown
mode for extended battery life. APower-OK opendrain output signals when V is in regulation.
OUT The AAT3216 is available in a space saving 5-pin SOT23 or 8-pin SC70-JW package in 12 factory
programmed voltages of 1.2V, 1.5V, 1.8V, 2.0V,2.3V, 2.5V, 2.7V, 2.8V, 2.85, 3.0V, 3.3V, or 3.5V.
