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
