Working Principle

The TPS74201KTWRG3 is a bipolar linear voltage regulator. It works by utilizing two feedback loops to maintain a controlled output voltage. The first feedback loop is an error amplifier, which senses any deviation between the setpoint and the actual output, and adjusts the gate voltage of an external P-channel MOSFET to maintain control of the output voltage. The second feedback loop is a timer-controllable shutoff feature which triggers an output shutoff when the input voltage falls below a programmable threshold. The device also includes an integrated power-on reset circuit that initiates upon power-up, which prevents the output voltage from being undershoot.

Conclusion

The TPS74201KTWRG3 is a low-power linear regulator designed for a wide range of applications that require low-noise, low-power and low-cost voltage regulation. It features a wide input voltage range of up to 20 volts, low dropout voltage, timer-controllable shutdown, and an integrated power-on reset circuit. These features make the TPS74201KTWRG3 an ideal choice for a variety of low-voltage applications.
