Show transcribed image text A simple Zener diode voltage regulator is under design. The design constraints are: Supply voltage - Vs = 150 V Zener voltage - Vz = 50 V Zener current range - 5 mA Iz 50 mA Determine the value of the regulator resistor, R, so that voltage regulation is maintained for a load current in the range: 1 mA IL IL(max). What is the maximum load current, IL(max)? What power rating is necessary for the resistor. R? If the variable load of part a is replaced by a 2 k Ohm resistor and the regulator is constructed using the resistor R calculated in pan a, over what range of supply voltages will regulation be maintained?
