Patent abstract
A voltage regulator has an output circuit for producing from an input voltage a predetermined output voltage to be supplied to a load, an overcurrent protection circuit for preventing overcurrent in the output circuit, a memory for storing control information fed from outside, and an adjustment circuit for adjusting the level at which the overcurrent protection circuit detects overcurrent according to the control information read from the memory. With this configuration, it is possible to accurately detect overcurrent by canceling factors such as individual variations in the characteristics of the circuit components, the influence of stress occurring when the regulator IC is packaged, and fabrication-associated variations in the load.
