Title:
ボルテージレギュレータ
Document Type and Number:
Japanese Patent JP4421909
Kind Code:
B2
Abstract:
The present invention provides a voltage regulator which has high-speed responsibility with a low consumption current, and which can stably operate with a low output capacity. The voltage regulator includes: a reference voltage circuit, a voltage division circuit, a differential amplifier, an output transistor, a MOS transistor which has a gate to which an output of the differential amplifier is connected, a constant current circuit connected between a drain of the MOS transistor and the ground, and parallel-connected resistor and capacitor for phase compensation are connected between the drain of the MOS transistor and a gate of the output transistor.
