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).
Absolute maximum ratings (Ta = 25C)
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.
