Working principle

AN7705SP-E1 is a three-terminal linear regulator that uses a P-MOSFET as the main element to achieve voltage regulation. The three pins are labeled IN, GND and OUT. The output voltage is determined by the feedback loop. The output voltage is adjusted by the resistors connected to the FB and GND pins. The voltage drop across the P-MOSFET is only 0.2V, so the line regulation is very good. The current limiting circuit of AN7705SP-E1 prevents the output current from exceeding 1 A. Within the specified limit, it will automatically limit the output current of the regulator to maintain the output voltage. In addition, a thermal shutdown circuit is built in AN7705SP-E1, which will stop operation when the device is too hot and automatically recover when the temperature drops.
