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 V_{Z} = 12V, I_{ZK} = 1mA I_{ZM} = 50mA and the diode has internal zener resistance of 5 ohmsV_{Z} = 15V at I_{Z} = 17mA, I_{ZK} = 0.25mA and Z_{Z} = 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
