Overview
The LV5683P is a multi voltage regulator suitable for USB silicon tuner car-audio systems. This IC has 4 outputs, VDD 5V(3.3V), AUDIO(8.5V), SWU(3.3V) and USB5V(CD 8V: available). About protection circuits, it has Over-current-protection, Over-voltage-protection and Thermal-shut-down. VCC1(SWU and USB supply) is independent terminal from VCC, and accepts lower voltage(ex. From DC/DC converter) which enables to reduce power dissipation.
