ABSTRACT:
An ultra low dropout voltage regulator, which separately supplies operating power for internal circuits, but controls the operating power to perform the operation of a voltage regulator chip, so that an ultra low dropout voltage regulator can be designed to reduce standby power consumption and to minimize the size of the chip, can be designed to more rapidly respond to the overload or overvoltage of the chip and to stably and precisely shut down the chip in the event of the overload or overvoltage, and can be designed to realize ultra low dropout characteristics even at a low output voltage.
