Product Description

The MPQ8903 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 MPQ8903 has thermal protection to guard against harsh operating conditions, and is available in 5-pin TSOT23 package.
