Overview
Description
The MIC2954 is a highly efficient voltage regulator with low dropout voltage (40mV at light loads, 375mV at 250mA) and low quiescent current (120μA typical). Its quiescent current increases only slightly in dropout, extending battery life.

Features
High-accuracy 5V output, guaranteed 250mA
Low quiescent current
Low dropout voltage
Tight load and line regulation
Very low temperature coefficient
Current and thermal limiting
Input withstands -20V reverse battery and 60V positive transients
Error flag warns of low output voltage
Logic-controlled electronic shutdown
Output programmable from 1.24V to 29V (MIC2954-07/08)
Available in TO-220, TO-92, SOT-223, and SOIC-8 packages

Applications
Battery-powered equipment
Cellular telephones
Laptop, notebook, and palmtop computers
PCMCIA Vcc and Vpp regulation/switching
Bar code scanners
Automotive electronics
SMPS post-regulator/dc-to-dc modules
Voltage reference
High-efficiency linear power supplies
