In addition, the device can be used in power back-up applications to supply power when the input power is lost.

The working principle of TPS79901DRVTG4 can be simplified to two transistors working in series to create a voltage reference. The non-inverting input is compared to the reference voltage provided by the transistors. If the input voltage is lower than the reference voltage, then the output voltage will be regulated to the reference voltage. When the input voltage is higher than the reference voltage, the output voltage will stay at the reference voltage. The output voltage is controlled by a P-channel MOSFET, which passes current through the reference transistors. The voltage regulator can control current up to 1.8A.

In summary, the TPS79901DRVTG4 is a 1.8A low-dropout linear regulator with ±2% output voltage accuracy. It can operate over a wide input voltage range and offers a variety of output voltages in the range of 1.2V to 3.3V. The device is suitable for automotive, industrial, and portable applications that require low output noise and low power consumption. The device also has protection functions such as over-current protection and thermal shutdown. The TPS79901DRVTG4 is an ideal solution for powering audio, video and computing devices in battery-powered, automotive and portable applications.
