Description
The HA13166H is a compact multiple voltage regulator for car audio system. The outputs of this IC output consist of regulated 5.7 V output for a microcontroller, regulated 3.3 V output for a digital signal processor, regulated 8 V output for CD driver, regulated 9.0 V output for audio control, regulated 10 V output for illuminations and regulated 5 V output, VCC-dependent output for external output and VCC-dependent output for remote-ANT.

Functions
General
•  ACC power monitor circuit is built-in.
•  Low saturation output (PNP output) used for audio output.
•  Adjustable voltage for illumination output by changing an external resistor.

Protections
•  Output current limit circuit to avoid device destruction caused by shorted output, etc.
•  High surge input protector against VCC and ACC.
•  Built in a thermal shutdown circuit to prevent against the thermal destruction.
