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.
