Abstract
A constant voltage generator includes a resistance adjustable resistor having a series connection of a main resistor and sub-resistors, a circuit cooperating with the series connection to produce a constant voltage, a plural number of transistors having a collector-emitter path connected to corresponding one of the sub-resistors, and a plural number of semiconductor memories applying voltages to bases of the transistors, respectively, in accordance with stored information, whereby the resistance of the resistance adjustable resistor is adjusted by the stored information to control the output constant voltage.
