System power supply for CD player­equipped audio systems

BA3963

With 5V and 7V outputs and a reset output that detects the 5V output, the BA3963 power supply IC is best suited for
CD player-equipped audio systems.

Applications
CD player-equipped audio systems

Features

1) A 5V output, a 7V output, and a reset output are built
in.

2) All output circuits use a PNP transistor with a low sat­uration voltage.

3) Current limit circuit protects the IC against short-cir­cuiting damage.

4) Thermal protection circuit prevents heat damage to
the IC.

5) Compact SIP-M12 package allows a large power dis­sipation.
