Function If VDD voltage becomes 4V or less.RESET output becomes low level. This output voltage is approximately 0.5V lower than VCC. and max output current is 300mA. A voltage supply for ACC block. This output voltage is approximately 0.7V lower than VDD'S. The max output current is 100mA. Control of the COMP output by inputting voltage. This output voltage is 5.7V, and max output current is 100mA. This voltage supply is for microcomputer. Whenever back up voltage supply is connected, the output keeps on running. This output voltage is 9.0v, and max output current is 500mA. This voltage supply for AUDIO. This output voltage is 8.0V, and max output current is 1A. This voltage supply for CD. Output selector of CD. AUDIO, ILM and EXT. To be connected with the BACK UP of car. This output voltage is 10V, and max output current is 500mA. Output voltage is adjustable. Putting a resistance between ILM and AJ or between AJ and GND makes ILM output voltage adjustable. Ground.
