Classification: CPC G  H | IPC G  H

Claim 9:
10. A circuit comprising:
a voltage regulator comprising:
a first transistor coupled between a voltage supply node and a first node;
a second transistor and a second switch coupled in series between the voltage supply node and the first node; and
an amplifier, wherein a first input terminal of the amplifier is configured to be coupled to a reference input voltage, and a second input terminal of the amplifier is coupled to the first node through a feedback network, wherein an output terminal of the amplifier is coupled to a first gate terminal of the first transistor and a second gate terminal of the second transistor;

a first load circuit coupled between the first node and a reference voltage node; and
a second load circuit coupled between the first node and the reference voltage node, wherein the voltage regulator is configured to, during normal operation of the circuit, open and close the second switch repeatedly in accordance with a load condition of the second load circuit, wherein the first load circuit is a first programmable delay circuit configured to receive a clock signal, wherein the second load circuit is a second programmable delay circuit configured to receive a data signal clocked by the clock signal, wherein the voltage regulator is configured to close the second switch for a period of time when a rising edge or a falling edge is detected in the data signal.
