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 sho...
