General Description

• The TDA3683J 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 TDA3683J 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.
