AAT3216

PowerLinearTM General Description The AAT3216 MicroPower low dropout (LDO) linear regulator is ideally suited for portable applications where low noise, extended battery life, and small size are critical. The AAT3216 has been specifically designed for low output noise performance, fast transient response, and high power supply rejection ratio (PSRR), making it ideal for powering sensitive RF circuits. Other features include low quiescent current, typically 70μA, and low dropout voltage, typically less than 200mV at full output current. The device is output shortcircuit 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 VOUT is in regulation. The AAT3216 is available in a Pb-free, space-saving 5-pin SOT23 or 8-pin SC70JW package in 12 factoryprogrammed voltages: 1.2V, 1.5V, 1.8V, 2.0V, 2.3V, 2.5V, 2.7V, 2.8V, 2.85V, 3.0V,...
