General Description
The AAT3216 MicroPower low dropout (LDO) lin-
ear regulator is ideally suited for portable applica-
tions where low noise, extended battery life, and
small size are critical. The AAT3216 has been
specifically designed for 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 70µA, and low dropout voltage, typically 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 V
The AAT3216 is available in a Pb-free, space-saving
5-pin SOT23 or 8-pin SC70JW package in 12 facto-
ry-programmed voltages: 1.2V, 1.5V, 1.8V, 2.0V,
2.3V, 2.5V, 2.7V, 2.8V, 2.85V, 3.0V, 3.3V, or 3.5V.
