LA5605
Monolithic Linear IC
For CD Radio Cassette Recorders
Power Supply System
Overview
The LA5605 is an AC/DC power supply IC that incorporates a 7.5V/500mA low saturation regulator and a number of
control functions. It is optimal for use as the power supply IC for CD radio cassette recorders and other applications.
Features
• Facilitates designing the AC/DC power supply system for CD radio cassette recorders.
• A wide variety of control circuits incorporated, which realizes further miniaturization in electronic products.
• The adoption of a low-saturation regulator circuit reduces internal power dissipation.
Functions
• Power supply system for CD radio cassette recorders
• For small electronic products
• Low saturation regulator (7.5V/500mA)
• Limiter power supply (9V/60mA)
