Abstract
A regulated voltage supply contains a zener diode controlled by a constant current generator to maintain the zener voltage at a constant level regardless of the swings of the voltage input to the diode. A current amplifier responds to the constant current generator to maintain the output voltage of the regulated voltage supply at the value of the zener voltage regardless of the demands of the load. A low voltage inhibit circuit responds to the magnitude of the input voltage and the magnitude of the voltage on the zener diode to generate a binary voltage signal for inhibiting the operation of a load such as a microcomputer when the voltage regulator is below the zener voltage level and the input is below the desired voltage.
