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 [ ... ]
