[Linear Dimensions, Inc.]

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-Thomson-L48XX 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
