AAT3215
150mA CMOS High Performance LDO
General Description
The AAT3215 MicroPower™ Low Dropout Linear
Regulator is ideally suited for portable applications
where low noise, extended battery life and small
size are critical. The AAT3215 has been specifi-
cally designed for very low output noise perform-
ance, fast transient response and high power sup-
ply rejection ratio (PSRR), making it ideal for pow-
ering sensitive RF circuits.
Other features include low quiescent current, typi-
cally 95µA, and low dropout voltage which is typi-
cally less than 140mV at full output current. The
device is output short circuit protected and has a
thermal shutdown circuit for additional protection
under extreme conditions.
The AAT3215 also features a low-power shutdown
mode for extended battery life. A reference bypass
pin has been provided to improve PSRR perform-
ance and output noise, by connecting an external
capacitor from the AAT3215's reference output to
ground.
The AAT3215 is available in a space saving 5-pin
SOT-23 or 8-pin SC70-JW package in 8 factory
programmed voltages of 2.5V, 2.7V, 2.8V, 2.85V,
2.9V, 3.0V, 3.3V, or 3.5V.
