GENERAL DESCRIPTION

This series of fixed-voltage monolithic micropower voltage regulators is designed for a wide range of applications. This device is an excellent choice for use in battery-powered application. Furthermore, the quiescent current increases only slightly at dropout, which prolongs battery life.

FEATURES

? 400mA output within 2 over

temperature

? Very low quiescent current

? Low dropout voltage (420mV Typ)

? Extremely tight load and line regulation

? Very low temperature coefficient

? Current and thermal limiting

? Unregulated DC input can withstand –

20V reverse battery and +60V positive

transients

? Direct replacement for SGS-ThomsonL48XX Series, but has lower ground

current, higher accuracy of output

voltage and extremely tight load and

line regulation. The 5 pin version

(adjust model) and 4 pin version (fixed

model) have a shutdown input.

APPLICATIONS

? High-efficiency linear regulator

? Battery powered systems

? Portable/palm top/ notebook

Computers

? Portable consumer equipment

? Portable instrumentation

? Automotive Electronics

? SMPS Post Regulator
