TDA3683 Multiple voltage regulator with switch and ignition buffer Rev. 02 — 7 October 2005 Product data sheet 1. General description • The TDA3683 is a multiple output voltage regulator with a power switch and an ignition buffer. Several protections and diagnostic options are incorporated in this design. • The TDA3683 is primarily developed to cover the complete power supply requirements in car radio applications. • The standby regulators (regulators 1, 2 and 3) are especially designed to supply digital circuitry that has to be permanently connected e.g. Controller Area Network (CAN) bus, Digital Signal Processor (DSP) core and the microcontroller.
