AAT3237 300mA MicroPowerTM LDO with PowerOK

The AAT3237 MicroPower low dropout (LDO) linear regulator is ideally suited for portable applications where low noise, extended battery life, and small size are critical. The AAT3237 has been specifically designed for low output noise performance, fast transient response, and high power supply rejection ratio (PSRR). Other features include low quiescent current, typically 70μA, and low dropout voltage, typically less than 400mV at full output current. The device is output short-circuit protected and has a thermal shutdown circuit for additional protection under extreme conditions. The AAT3237 also features a low-power shutdown mode for extended battery life. A Power-OK open-drain output signals when VOUT is in regulation. The AAT3237 is available in a Pb-free, space-saving 6-pin SOT23 or 8-pin SC70JW package in 13 factory-programmed voltages: 1.2V, 1.5V, 1.8V, 2.0V, 2.3V, 2.5V, 2.7V, 2.8V, 2.85V, 2.9V, 3.0V, 3.3V, or 3.5V.
