Abstract
Provided is a variable output voltage regulator capable of reducing heat generation during an overcurrent protection operation even when a setting value of an output voltage is high. The variable output voltage regulator can change an output voltage by trimming a resistor of a voltage dividing circuit in response to a trimming signal output from a trimming signal generation circuit. The trimming signal is used to change a limiting voltage of a fold-back type overcurrent protection circuit.
