Abstract:
Disclosed herein are a circuit of outputting a temperature compensation power voltage from variable power and a method thereof, the circuit including: a regulator circuit unit converting the variable power into a predetermined voltage desired by a system; a resistance compensation circuit unit provided at an output terminal of the regulator circuit unit, and compensating for a change in resistance value due to the temperature change; and a temperature sensor sensing a change in surrounding temperature of an electronic circuit system employing the regulator circuit unit and supplying an output value corresponding to the sensed temperature change to the resistance compensation circuit unit, to thereby allow the resistance compensation circuit unit to compensate for the change in resistance value due to the temperature change.
