MP8802DJ2.5

Low Dropout 250mA Linear Regulator

Monolithic Power Systems 

The Future of Analog IC Technology

DESCRIPTION

The EV8802DJ-00A is the evaluation board for

the MP8802. The board is configured with the

MP8802DJ2.5, which provides an output

voltage of 2.5V.

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 to

fixed values of 2.5V, 2.85V, 3.3V or from 1.5V

to 5V with the use of external resistors.

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.
