LV5684NPVD: 5-Channel Linear Voltage Regulator with 2 High-Side Switches for Automotive Infotainment

The LV5684NPVD is a multiple output linear regulator IC, which allows reduction of quiescent current. The LV5684NPVD is specifically designed to address automotive infotainment systems power supply requirements. The LV5684NPVD integrates 5 linear regulator outputs, 2 high side power switches, over-current limiter, overvoltage protection and thermal shut down. Supply for VDD and SW33V outputs is low voltage specification, which enables drastic reduction of power dissipation compared to the existing model.

Features

Low consumption current: 50uA (typ, only VDD output is in operation)
VDD for microcontroller: output voltage: 3.3V, maximum output current: 350mA
For system: output voltage: 3.3V, maximum output current: 450mA
For audio: output voltage: 5 to 12V (set by external resistors), maximum output current: 250mA
For illumination: output voltage: 5 to 12V (set by external resistors), maximum output current: 300mA
