LP2951A Datasheet PDF - Semtech Corporation

DESCRIPTION
The LP2951A is an improved version of the LP2951 and features tighter tolerance on the output voltage and reference voltage specifications. Both the LP2951 and LP2951A feature 150mA output current capability. 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 output @150mA
• Low dropout voltage - 450mV @ 150mA
• Regulator or reference functions
• Direct replacement for LP2951AC, MIC2951-02, AS2951AC

APPLICATIONS
• Microcontroller supplies
• Linear regulators
• Adjustable supplies
• Switching power supplies - post-regulation
• Portable modems
• Battery powered systems
• Cellular telephones
• Voltage references
