Abstract
An adaptable LDO regulator includes an error amplifier providing an error voltage according to a difference between a feedback voltage and a reference voltage, first and second pass transistors each having a first current electrode for receiving an input voltage, a control electrode for receiving the error voltage, and a second current electrode, the second current electrode of the second pass transistor providing an output voltage, a voltage divider generating the feedback voltage in response to a voltage on an input thereof, and a mode selection network that in a closed loop mode, couples the second current electrodes of the first and second pass transistors together and to the input of the voltage divider, and in an open loop mode, couples the second current electrode of the first pass transistor to the input of the voltage divider and decouples the second current electrodes of the first and second pass transistors.
