Working Principle of TPS79118DBVT

TPS79118DBVT works on the principle of Linear voltage regulators. The basic principle is to first convert the input voltage into a perfectly regulated output voltage with a very low dropout voltage. To do this, the regulator works with negative feedback. It compares the output voltage with the reference voltage and if the output voltage deviates from the reference voltage, it will adjust constantly adjust its output voltage to maintain its set value.

The Linear voltage regulator controls the current with a series resistor. It measures the voltage over the series resistor and adjusts its output current to keep the voltage constant. This method works well with linear regulators, but it is not the most efficient way of regulating the current.

The TPS79118DBVT is a very high-efficiency voltage regulator that provides excellent performance for low voltage applications. It is designed to operate over wide input voltage ranges and provides very accurate output voltage control. It also has very low standby current consumption and good thermal protection.
