General Description
The AAT3238 MicroPower Low Dropout Linear
Regulator is ideally suited for portable applications
where very fast transient response, extended battery
life and small size are critical. The AAT3238 has
been specifically designed for high speed turn on and
turn off performance, fast transient response, good
power supply ripple rejection (PSRR) and is reason-
ably low noise, making it ideal for powering sensitive
circuits with fast switching requirements.
Other features include low quiescent current, typical-
ly 70μA, and low dropout voltage which is typically
less than 400mV at the maximum output current level
of 300mA. The device is output short circuit protect-
ed and has a thermal shutdown circuit for additional
protection under extreme operating conditions.
The AAT3238 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 a small exter-
nal capacitor from the AAT3238's reference output to
ground.
The AAT3238 is available in a space saving 6-pin
SOT23 or 8-pin SC70JW package in 14 factory pro-
grammed voltages of 1.2V, 1.5V, 1.6V, 1.8V, 1.85V,
2.0V, 2.3V, 2.5V, 2.7V, 2.8V, 2.85V, 3.0V, 3.3V or
3.5V.
