Abstract
According to the present invention, an integrated regulator having an adjustable reset threshold is disclosed. The integrated regulator has the following elements contained within an integrated circuit device: a transistor, a voltage reference block, an internal resistive network, an operational amplifier which regulates the voltage output signal of the integrated regulator by regulating the base current of the transistor, and a comparator which senses and communicates to the user when the operational amplifier is unable to maintain the voltage output signal within an acceptable range of a desired value of the voltage output signal. External to the integrated circuit device is an external resistive network. When the reset output signal of the integrated regulator is equal to an active state, this is indicative that the operational amplifier has been unsuccessful in keeping the voltage output signal within the acceptable range of the desired value of the voltage output signal, i.e. the voltage output signal has fallen below the reset threshold or trip point of the integrated regulator. When the voltage output signal is back within the acceptable range of the desired value of the vol…
