DESCRIPTION

The MP8801 is a low-noise, low-dropout linear regulator. It operates from a 2.7V to 6.5V input voltage (VIN) and regulates the output voltage (VOUT) with 2% accuracy at 2.5V, 2.85V or 3.3V. The internally set VOUT can be overridden via an external resistor divider from 1.25V to 5V.

The MP8801 can supply up to 150mA of load current. It also features thermal shutdown, and is available in a TSOT235 package.
