Monolithic Linear IC

LA5633

Satellite Broadcast (BS/CS) Tuner Regulator IC

Overview

The LA5633 is a low-saturation regulator IC designed for use in satellite broadcast tuners (such as tuners for the Japanese BS and CS systems) and provides four controllable outputs.

Applications

•Power supply systems in BS/CS tuners

•Audio Video (AV) equipment that includes any type of satellite broadcast tuner

•Miniature electronic equipment

Functions

•Built-in four regulators of low-saturation output (15.7 V/350 mA, 9 V/250 mA, 12 V/100 mA, 5 V/650 mA)

•Output on/off control (active low)

•On-chip thermal protection and overcurrent protection circuits

Features

•Provides all four voltages required by BS/CS tuners, and thus can contribute to end product miniaturization.

•VO1 can be controlled independently, and VO2, VO3, and VO4 are controlled together, thus providing a high degree of flexibility in system design.

•The adoption of a low-saturation regulator circuit reduces internal power dissipation.

•Provides 3 inputs to make both low-power design and thermal design easy.

Any and all SANYO products described or contained herein do not have specifications that can handle applications that require extremely high levels of reliability, such as life-support systems, aircraft’s control systems, or other applications whose failure can be reasonably expected to result in serious physical and/or material damage.
