Design a zener shunt regulator. Enter supply voltage (with variation), zener voltage, max load current and minimum zener current. Get the series-resistor window -not a single value, because Rs must handle both full-load and no-load -plus dissipation and efficiency.

How to use
What it's for
Design a zener shunt regulator: the series-resistor window, power ratings and safety margin.
You enter
Supply voltage (nominal, with its variation), zener voltage, maximum load current, minimum zener current.
You get
The window the series resistor Rs must fall inside (pass enough current at full load without cooking the zener at no load).
Rs dissipation, zener dissipation in the worst and leanest cases, and stage efficiency.
