Hi,
I'm trying to use a zener diode (18.5V) reverse bias to ground with a source voltage that can range from 9 V to 30 V...I basically want the diode to conduct and regulate the voltage to 18.5 once the voltage gets that high. I'm using a 1 k resistor in series with the source, but get a very small voltage on the output (other side of resistor / zener diode), can anyone explain what may be going on? The current I'm drawing needs to support 2 amps atleast.
