1 / 7 page MP8801 Low Dropout 150mA Linear Regulator MP8801 Rev. 1.6 www.MonolithicPower.com 1 3/6/2006 MPS Proprietary Information. Unauthorized Photocopy and Duplication Prohibited. © 2006 MPS. All Rights Reserved. The Future of Analog IC Technology DESCRIPTION The MP8801 is a low-noise, low-dropout linear regulator. It operates from a 2.7V to 6.5V input voltage and regulates the output voltage with 2% accuracy at 2.5V, 2.85V or 3.3V. The internally set output voltage may be overridden with an external resistor divider from 1.25V to 5V. The MP8801 can supply up to 150mA of load current. The MP8801 features thermal overload protection and is available in a 5-pin TSOT23-5 package.
