Abstract
A level adjusting circuit for controlling a voltage supplied to a load such as a semiconductor device, which comprises a voltage level detecting circuit, a reference potential generating circuit for generating a pair of reference potential values to be output into the voltage level detecting circuit, and a monitor pad for drawing out the voltage supplied to the load, wherein the reference potential values are respectively used to compare with the voltage to thereby output a signal for starting supply of the voltage and a signal for ceasing the supply of the voltage under a usually used condition; and the voltage level detecting circuit is to compare either one of the reference potential values with the voltage or the other reference potential value with the voltage at a time under a testing condition, whereby the reference potential generating circuit can accurately be adjusted to change the reference potential values to render the voltage in a range permissible for operation of the load.
