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. Consult with your SANYO representative nearest you before using
any SANYO products described or contained herein in such applications.
SANYO assumes no responsibility for equipment failures that result from using products at values that
exceed, even momentarily, rated values (such as maximum ratings, operating condition ranges, or other
parameters) listed in products specifications of any and all SANYO products described or contained
herein.
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.
