DESCRIPTION

The LP2951 series of low power voltage regulators have low quiescent current and low dropout voltage. The quiescent current increases minimally during dropout conditions thereby extending battery life.

FEATURES

• Guaranteed 150mA current

• Adjustable output voltage - 1.24V to 29V

• Accurate 5V or 3.3V output @ 100mA

• Low dropout voltage - 350-400mV @ 100mA

• Regulator or reference functions

• Direct replacement for LP2951C, MIC2951-03, AS2951C

APPLICATIONS

• Microcontroller supplies

• Linear regulators

• Adjustable Supplies

• Switching power supplies - post-regulation

• Portable modems

• Battery powered systems

• Cellular telephones

• Voltage references
