Features

1) A power supply IC for car audio systems ; one 5.6V output for microcontrollers, three 8.7V outputs, and two outputs interlocked with BACKUP and ACC systems are built in. 2) All output circuits use a PNP transistor with a low saturation voltage. 3) Output current limit circuit prevents damage to the IC in the event output is short-circuited. FBlock diagram 4) Overvoltage protection circuit provides protection against surges from the ACC or BACKUP inputs. 5) Compact 12-pin POWER package allows.
