The TPS43331 is a multi-rail output voltage regulator with two synchronous switch-mode controllers and two linear regulators. In addition, there is a protection monitoring standby input voltage regulator and a high-side switch and a voltage monitor reverse. This regulator output, control of the high-side switch, or use of discrete inputs in an I2C configuration that is not controlled by a discrete input output through certain outputs and serial interfaces.

Standby linear regulators (VSTBYs) are high voltage tolerant and can be connected directly to the automotive battery and maintain a regulated output at a typical and light load with a quiescent current of 65μA.
