Power supply for CD radio cassette players
BA3924
The BA3924 is a system reference power supply for use in CD radio cassette players. Outputs dedicated to a microprocessor (5.0V), CD player (7.5V), audio system (7.5V), and motor drive (9V) are built in. Also built in is a VCC)B output that allows turning ON and OFF the supply voltage by HIGH and LOW levels of the standby pin.
FApplications CD radio cassette players
FFeatures 1) With outputs dedicated to a microcontroller, CD player, audio system, and motor drive, the IC is best suited for CD radio cassette players. 2) Zero standby current (typ.). 3) Output current limit circuit protects the IC against short-circuiting damage.
4) Compact 12-pin package allows large power dissipation.
