LA5609

Multi-Function Voltage Regulator for Radio Cassette Recorders with CD Player

Overview

The LA5609 is a multi-function multi-voltage power supply that includes a built-in on/off function. The LA5609 provides dedicated outputs for motors, audio systems, CD drive, radio, microprocessor, and loading drives, thus making it optimal for use as the system power supply in radio cassette recorders with CD player.

Functions

•Power supply systems for radio cassette recorders with CD player

•Miniature electronic equipment

•Low-saturation regulator (14.5 V/1.2 A, 9 V/300 mA, 7.5 V/800 mA)

•High-precision power supply (two 5 V/220 mA systems, 5 V/100 mA, 8 V/800 mA)

•Limiter power supply (9 V/60 mA)
