General Description
The AAT3216 MicroPower low dropout (LDO) linear 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 performance, fast transient response, and high power supply rejection ratio (PSRR), making it ideal for powering sensitive RF circuits.
