Abstract: In one example, a method for compensating for a temperature effect during operation of a voltage regulator circuit includes applying a load current at an output of the voltage regulator circuit, measuring a first output voltage at the output, measuring a reference current or voltage, increasing the load current, measuring a change in the reference current or voltage corresponding to the increased load current, measuring a second output voltage when the measured change in the reference current exceeds a threshold, and determining a temperature coefficient (TC) value based on the measured second output voltage.
