The BA3932 is a monolithic reference voltage power supply IC for use in CD radio cassette players.
BA3932 Features
1) With 9.0V output for audio power supply, 5.0V output for microcontrollers, 5.0 and 8.0V outputs for CD players, 14.7V output for motor drivers, the IC is best suited for CD radio cassette players. 2) Precise power supply (5V ± 0.1V) can be obtained by using external reference voltage input (only AUDIO output has an internal reference voltage system). 3) Zero standby current. (Typ.) 4) Output current limit circuit protects the IC against short-circuiting damage. 5) Compact SIP-M12 package allows a large power dissipation (3W: no heat sink). 6) Thermal protection circuit prevents heat damage to the IC.
BA3932 Typical Application
CD radio cassette players, mini-component stereo audio systems
