Verify the minimum & maximum load current for which the zener diode will keep regulation. Find the minimum value of RL that can be used.
The zener diode has VZ = 12V, IZK = 1mA IZM = 50mA and the diode has internal zener resistance of 5 ohmsVZ = 15V at IZ = 17mA, IZK = 0.25mA and ZZ = 14 ohms and PD(max) = 1W
a) Find VOUT at IZK and IZM
b) Determine the value of R that should be used
c) Calculate the minimum value of RL that can be used
d) Find the minimum & maximum value of load current
e) Locate the line regulation
