Abstract

See full text

Described embodiments include a circuit for controlling a voltage drop. The circuit includes a resistor coupled between an output voltage terminal and a reference voltage terminal. First, second and third switches each have respective first, second and third switch terminals. The respective second switch terminals are connected together and are coupled to the output voltage terminal. The respective third switch terminals are connected together and are coupled to the reference voltage terminal. A first transistor is coupled between a supply voltage terminal and the first switch. A second transistor is coupled between the supply voltage terminal and the second switch. A third transistor is coupled between the supply voltage terminal and the third switch. Control terminals of the first, second and third transistors are coupled to a gate control terminal.
