LV5684NPVD数据手册集成电路（IC）的特殊用途稳压器规格书PDF

描述 Description

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.
