Voltage regulator with over-current protection |
摘要 |
A linear regulator with an N-type pass transistor includes an over-current protection circuit. A current sink is used as an indicator for an over-current condition and is coupled to the output of the linear regulator. The indicator is coupled to a feedback logic circuit that controls the current through the output load. The over-current protection circuit extensively uses N-type devices for various components including the output driver stage in the circuit. This results in reduced area for the over-current protection circuit.
