  • Regulator and organic light emitting diode display using the same
    Patent number: 8817007
    Abstract: A regulator and an organic light emitting diode display including the regulator are disclosed. The regulator includes a reference voltage generating unit generating a reference voltage from an input voltage, a voltage division resistor circuit dividing a voltage of an output terminal of the regulator to generate a feedback voltage, a comparator comparing the reference voltage with the feedback voltage, a transistor that is turned on or off based on an output of the comparator and switches on or off the input voltage supplied to the output terminal, and a sink current breaking circuit for discharging a sink current flowing in the output terminal to a ground level voltage source.
    Type: Grant
