Negative Voltage Reference Circuit

Posted on Feb 4, 2014

This circuit is a Adjustable voltage reference circuits, a voltage source which provides a voltage greater than the reference diode. High precision extended temperature applications of the circuit require that the range of adjustment of VOUT be restricted. When this is done, R1 may be chosen to provide optimum zener current for minimum zener T. C.

Since IZ is not a function of V+, reference T. C. will be independent of V+. Here is a schematic drawing :
