Claim 0:
1. A circuit for controlling a voltage drop, the circuit comprising:
a resistor coupled between an output voltage terminal and a reference voltage terminal;
first, second and third switches, each switch having respective first, second and third switch terminals, the respective second switch terminals connected together and coupled to the output voltage terminal, and the respective third switch terminals connected together and coupled to the reference voltage terminal;
a first transistor coupled between a supply voltage terminal and the first switch terminal of the first switch, and having a first control terminal coupled to a gate control terminal;
a second transistor coupled between the supply voltage terminal and the first switch terminal of the second switch, and having a second control terminal coupled to the gate control terminal; and
a third transistor coupled between the supply voltage terminal and the first switch terminal of the third switch, and having a third control terminal coupled to the gate control terminal.
