The AAT3215 MicroPower Low Dropout Linear Regulator is ideally suited for portable applications where low noise, extended battery life, and small size are critical. The AAT3215 has been specifically designed for very 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 95A) and low dropout voltage, typically 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 performance and output noise, by connecting an external capacitor from the reference output to ground. The AAT3215 is available in a space-saving 5-pin SOT23 or an 8-pin SC70JW package in ten factory-programmed voltages.
