Abstract
Embodiments disclosed herein provide for a voltage regulator having one or more Zener diodes coupled in series between an output voltage and system ground. The one or more Zener diodes are in a reverse biased configuration. A transistor is coupled in series with the one or more Zener diodes between the one or more Zener diodes and system ground. A control circuit is coupled to the transistor and configured to adjust the transistor to control a voltage level of the output voltage. The control circuit is configured such that transistor is adjusted substantially independent of values of the one or more Zener diodes.
