Reference voltage power supply

BA3932

The BA3932 is a monolithic reference voltage power supply IC for use in CD radio cassette players.

Applications

CD radio cassette players, mini-component stereo audio systems

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 dis-

sipation (3W: no heat sink).

6) Thermal protection circuit prevents heat damage to

the IC.
