Working Principle

The TS14002-C025DFNR works by using a P-channel MOSFET (in place of the usual bipolar PNP device) as the pass element, allowing for lower dropout than bipolar devices and higher performance at low-output currents. When the device is enabled, the MOSFET passes current from the input to the output, producing a regulated output voltage. Additionally, an internal error amplifier is used to sense the difference between the output voltage and the reference voltage and to modify the gate voltage of the MOSFET accordingly, compensating for changes in load current or input voltage.
