  • Voltage regulator start-up circuit
    Patent number: 4740742
    Abstract: A start-up circuit for a voltage regulator having a first current mirror for providing start-up current and a second current mirror responsive to voltage output from said regulator for turning off said first current mirror when said regulator is close to regulation. The circuitry providing start-up current and the circuitry turning off the start-up current having substantially the same temperature coefficients.
