Overview

The LA5606N is a low saturation regulator IC for BS/CS tuner applications, equipped with four regulators capable of ON/OFF control.

Applications

• BS/CS tuner power supply system.

• Audio Video (AV) equipment with BS/CS receivers.

• Compact electronic equipment.

Functions

• Four low saturation regulators (15.7 V/300 mA, 12 V/150 mA, 9 V/100 mA and 5 V/500 mA).

• Output on/off control (“L” active).

• On-chip protective circuitry (current limiter, thermal shutdown).

Features

• Supports compact set design while incorporating four regulators needed by BS/CS tuners.

• Flexible system design by independent on/off control of VO1, VO4, as well as VO2 and VO3 pair.

• Reduces internal loss by employment of low saturation regulators.

• Adapting three input pins contributes power dissipation reduction and heat sink design.
