Filed: 2020-06-22
Abstract: A low voltage drop regulator includes an error amplifier, a buffer, a power transistor, a feedback circuit, a monitoring circuit, and an adaptive pole control circuit. The error amplifier compares a reference voltage and a feedback voltage, and generates a first error voltage based on the comparison. The buffer is connected to an output terminal of the error amplifier, and buffers the first error voltage to output a second error voltage. The power transistor has a gate connected to an output terminal of the buffer, and provides an output voltage to an output node by regulating an input voltage based on the second error voltage. The feedback circuit is coupled between the output node and a ground voltage, and divides the output voltage to provide the feedback voltage. The monitoring circuit is connected to the output terminal of the buffer in parallel with the power transistor, and generates a control voltage based on the second error voltage and the input voltage. The adaptive pole frequency adjustment circuit is connected between the output terminal of the error amplifier and the ground voltage, and selectively connects a regulating capacitor between the first intermediate node and the ground voltage in response to the control voltage.
