General Description

The MIC2954 is a “bulletproof” efficient voltage regulator with very low dropout voltage (typically 40mV @ light loads and 375mV @ 250mA), and low quiescent current (120μA typical). The quiescent current of the MIC2954 increases only slightly in dropout, thus prolonging battery life. Key MIC2954 features include protection against reversed battery, fold-back current limiting, and automotive load dump protection (60V positive transient).

Features

? High-accuracy 5V, guaranteed 250mA output

? Low quiescent current

? Low dropout voltage

? Extremely tight load and line regulation

? Very low temperature coefficient

? Current and thermal limiting

? Input can withstand –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, and surface-mount 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
