General Description

The AAT3215 MicroPower™ low dropout (LDO)

linear regulator is ideally suited for portable appli-

cations where low noise, extended battery life, and

small size are critical. The AAT3215 has been

specifically designed for very low output noise per-

formance, 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 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 Pb-free, space-saving

5-pin SOT23 or 8-pin SC70JW package in ten fac-

tory-programmed voltages: 2.5V, 2.6V, 2.7V, 2.8V,

2.85V, 2.9V, 3.0V, 3.1V, 3.3V, or 3.6V.
