BA3924 Datasheet Power supply for CD radio cassette players

Manufacturer: ROHM

Overview: Regulator ICs Power supply for CD radio cassette players BA3924 The BA3924 is a system reference power supply for use in CD radio cassette players. Outputs dedicated to a microprocessor (5.0V), CD player (7.5V), audio system (7.5V), and motor drive (9V) are built in. Also built in is a VCC)B output that allows turning ON and OFF the supply voltage by HIGH and LOW levels of the standby pin.

General Description

s BA3924 143 Regulator ICs BA3924 144 Regulator ICs FElectrical characteristics (unless otherwise noted, Ta = 25_C, VCC = 12V) BA3924 145 Regulator ICs BA3924 146 Regulator ICs FMeasurement circuits BA3924 147 Regulator ICs FCircuit operation BA3924 148 Regulator ICs FApplication example BA3924 149 Regulator ICs FOperation notes (1) Operating power supply voltage When operating within the proper ranges of power supply voltage and ambient temperature, most circuit functions are guaranteed.

Although the rated values of electrical characteristics cannot be absolutely guaranteed, characteristic values do not change drastically within the proper ranges.

When the supply voltage becomes less than the sum of the minimum I / O voltage differential and each output voltage, the reference power supply will not function any more.

Key Features

  • 1) With outputs dedicated to a microcontroller, CD player, audio system, and motor drive, the IC is best suited for CD radio cassette players. 2) Zero standby current (typ. ). 3) Output current limit circuit protects the IC against short-circuiting damage. 4) Compact 12-pin package allows large power dissipation. 5) Thermal shutdown circuit protects the IC against thermal damage. 6) VCC)B output allows turning ON and OFF the power supply voltage by HIGH and LOW levels of the standby pin. FAbsol.
