DESCRIPTION

The MP8802 is a low-noise, low-dropout linear

regulator. It operates from 2.7V to 6.5V input

voltage, and regulates the output voltage with

2% accuracy at 2.5V, 2.85V, 3.3V, or from

1.25V to 5V.

The MP8802 can supply up to 250mA of load

current. The MP8802 features thermal overload

protection. It is available in a 5-pin TSOT23-5

package.
