A simple Zener voltage regulator is required to provide a steady regulated
output voltage of 10 V under a maximum load of 80 mA, while the input
voltage to the regulator varies between 12 V and 14 V.
17.1 Calculate the maximum rated current value of a Zener diode to be
used
17.2 Calculate the minimum power for the Zener that could be used
safely.
17.3 If a 5 W rated Zener were to be used in this circuit:
(i) Calculate the maximum rated current value of a Zener device
to be used
(ii) Calculate the range of possible RS. limiting resistor values.
(iii) Suggest a suitable standard E12 resistor value
