illustrate

The TPS43331 is a multirail output voltage regulator with two synchronous switch-mode controllers and two linear regulators. In addition, there are protection monitoring standby input voltage regulators and high-side switches and voltage supervisor reverses. The regulator output, control of the high-side switch, or discrete input through certain outputs and serial interfaces using I2C that is not controlled by discrete input outputs.

The Standby Linear Regulator (VSTBY) is a high voltage tolerant, can be connected directly to the automotive battery, and maintains a regulated output at a typical quiescent current of 65μA and maintains a regulated output at light loads.
