Sanyo LA5609 Specifications

Ordering number : EN4786

20695TH (OT) No. 4786-1/8

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)

Features

• Supports end-product miniaturization by the provision of built-in control circuits.

• Provides reduced internal power dissipation by the adoption of a low-saturation regulator.

• Built-in output current limiter prevents IC destruction due to output shorts.
