Working Principle

The TPS70702PWPRG4 is based on a traditional double-transistor voltage regulator topology. It consists of two transistors: one for the voltage reference and one for the current sense. The output voltage is determined by a series of resistors connected to the reference transistor. The output voltage is monitored with a bandgap reference. When the output voltage drops too low, the current sense transistor activates to increase the output voltage. Similarly, if the output voltage rises too high, the current sense transistor shuts off to reduce the output voltage.

The TPS70702PWPRG4 provides excellent ripple rejection and high accuracy. It incorporates an on-chip power MOSFET, current-limit protection, and thermal-shutdown protection. Additionally, it includes a range of safety features such as input voltage and output voltage monitoring, output current monitoring, and overtemperature monitoring.

The TPS70702PWPRG4 is a high-performance, low quiescent current linear voltage regulator. It provides exceptional accuracy, low dropout voltage, low temperature coefficient, and excellent stability over a wide temperature range. With built-in protection features, it is ideal for cost-sensitive, low- to medium-power applications.
