MP8802
Low Dropout
250mA Linear Regulator
The Future of Analog IC Technology
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.
