AAT3216
150mA MicroPower™ LDO with PowerOK
General Description
The AAT3216 MicroPower™ 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, typi-
cally 70µA, and low dropout voltage which is typi-
cally 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. A Power-OK open-
drain output signals when VOUT is in regulation.
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.
