Reference voltage power supply
BA3935
The BA3935 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 9V output for audio power supply, 5V output for microcontrollers, 5V output for radio, 5 and 7.5V outputs for CD players, 9.5V 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).
