LV56851UV
Linear Voltage Regulator, Multiple-Output,
System Power Supply IC,
for Automotive Infotainment System
Overview
The LV56851UV is a multiple output linear voltage regulator IC, which allows
reduction of quiescent current. The LV56851UV is specifically designed to
address automotive infotainment systems power supply requirements.
The LV56851UV integrates 5 linear regulator outputs, 1 high side power switch,
I2C-bus communication, ACC detection, battery voltage detection, over-current
limiter, overvoltage protection and thermal shut down.
