<P>PROBLEM TO BE SOLVED: To provide a voltage regulator through which a large current never flows even if a battery 110 is connected in a positive/negative reversed state. <P>SOLUTION: The voltage regulator employs such a circuit configuration that a substrate potential (n-well) of an output transistor 103 of the voltage regulator is not VDD terminal fixed and a power source of a reference voltage circuit 101 and an error amplifier 102 does not have a VDD terminal fixed. <P>COPYRIGHT: (C)2013,JPO&INPIT |
