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.
Package Dimensions
unit: mm 3109-SIP18H
[LA5609]
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)
SANYO: SIP18H
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.

Test Circuit
Note: * This diode is required for bringing up the CD 8 V regulator.
No. 4786-5/8
LA5609 Sample Application Circuit
Note: 1. The diode in the 9 V limiter block must be added. It is required for preventing current from flowing into the 9 V limiter from the backup battery when VCC is off. 2. The diode and resistor between the CD 5 V and CD 8 V blocks must be added. It is required to bring up the CD 8 V regulator. 3. External noise can be limited and ripple rejection can be improved by adding an electrolytic capacitor between the audio 9 V and the filter circuits. 4. The electrolytic capacitors between VCC and GND and between each V0 and GND should have capacitances at least those shown in the diagram. Use Sanyo HW Series aluminum electrolytic capacitors or equivalent products.
