HA13166H

HA13166H Multiple Voltage Regulator for Car Audio REJ03F0224-0100 Rev.1.00 Jan 16, 2007 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.
