Reference voltage power supply

BA3933

The BA3933 is a monolithic reference voltage power supply IC for use in CD radio cassette players.

FApplications

CD radio cassette players, mini-component stereo audio systems

FFeatures

1) With 7.5V output for audio power supply, 5V output

for microcontrollers, 5V output for radio 5 and 7.5V

outputs for CD players, 9V 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.
