Product Description

The MP8903 is a 150mA low-dropout linear regulator that can operate from 2.7V to 6.5V input. It regulates the output with 2% accuracy and comes with preset 2.5V, 2.85V or 3.3V output. An external resistor divider may be used to adjust the output voltage from 1.25V to 5V. The MP8903 has thermal protection to guard against harsh operating conditions, and is available in small QFN8 (2x2mm) and 5-pin TSOT23 packages.
