Claim 0:
1. A circuit for dampening overshoot in a voltage regulator, the circuit comprising:
a first offset voltage circuit having a first offset input and a first offset output, the first offset input coupled to an input voltage terminal;
a second offset voltage circuit having a second offset input and a second offset output, the second offset input coupled to the input voltage terminal;
a first comparator having first and second comparator inputs and a first comparator output, the first comparator input coupled to the first offset output, and the second comparator input coupled to a reference voltage terminal;
a second comparator having third and fourth comparator inputs and a second comparator output, the third comparator input coupled to the second offset output, and the fourth comparator input coupled to a voltage regulator output;
an OR gate having first and second logic inputs and a logic output, the first logic input coupled to the first comparator output, and the second logic input coupled to the second comparator output; and
a turn-off circuit having a turn-off input and a turn-off output, the turn-off input coupled to the logic output, and the turn-off circuit configured to provide a turn-off signal at the turn-off output to stop current flow from the voltage regulator output responsive to a logic high at the turn-off input.
