Reference voltage power supply
BA3932
The BA3932 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 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.
FAbsolute maximum ratings (Ta = 25_C)
FRecommended operating conditions

FCircuit operation
(1) Timing chart
(2) Estimate of allowable power dissipation
Except under transitional conditions, the power dissipa-
tion of this IC is 3W per unit at 25_C. See Fig. 3 for heat
reduction characteristics, including some cases where
heat sinks are used.
AUDIO 9V, MOTOR 14.7V, and COM 5V are output re-
gardless of MODE SW.
RADIO 5V rises when MODE SW is 1.4V (typical), and
CD 8V and CD 5V rise when MODE SW is 3.2V (typical).
