LINEAR POWER SUPPLY CIRCUIT
DRIVE
January 13, 2022
A linear power supply circuit includes: an output stage including a first output transistor and a second output transistor, which are provided between an input terminal to which an input voltage is able to be applied and an output terminal to which an output voltage is able to be applied and are connected in parallel to each other; a driver configured to drive the first output transistor and the second output transistor based on a difference between a voltage based on the output voltage and a reference voltage; a resistor inserted between a gate of the first output transistor and a gate of the second output transistor; a capacitor having one end connected to the input terminal and the other end connected to a connection node between the resistor and the gate of the second output transistor; and a clamp element connected in parallel to the resistor.
