Title: Low dropout regulator having a current-limiting mechanism
Inventor: HSIEH HSIEN-CHENG
IPC: G05F1/10
Filed: 2008-10-20
Abstract: A low dropout regulator having a current-limiting mechanism is disclosed. The regulator includes a sensing resistor, an error amplifier, and first through fourth transistors. The first transistor generates an output voltage according to an input voltage and a current control signal. The sensing resistor is employed to generate a sense voltage based on the current flowing through the fourth transistor so as to control the second transistor for generating an internal voltage. The third transistor controls the current control signal based on a voltage divided from the internal voltage. The channel width/length ratio of the first transistor is greater than that of the fourth transistor. When the third transistor is turned off, the error amplifier adjusts the voltage of the current control signal according to a voltage divided from the output voltage; when the third transistor is turned on, the voltage of the current control signal is not adjusted.
