Title: Voltage regulator
Inventor: MATSUSHITA YUICHI
IPC: G05F3/28
Filed: 2004-03-02
Abstract: <P>PROBLEM TO BE SOLVED: To provide a voltage regulator for preventing the generation of any large output fluctuation due to overshoot or the like even when a applied power supply voltage is beyond a prescribed input voltage range.  <P>SOLUTION: When a power source potential VCC is lower than a desired DC voltage OUT, the potential of a node N3 of a reference potential adjusting part 50 is made lower than a reference potential REF. Thus, the output of a reference potential generating part 20 is drawn through an NMOS54 to a node N3, and a reference potential REF is decreased to the same potential as a control voltage VC. Thus, a differential amplifying part 30 is turned into a balanced state, and the ON resistance of a PMOS41 of an output part 40 is increased, and currents hardly flows. Therefore, even when the power source potential VCC is rapidly increased to a prescribed voltage, any transient excessive currents can be prevented from flowing through a PMOS 41, and a stable DC voltage OUT can be obtained.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
