Design a +10 V supply with the same specifications as in Exercise 2.6. a zener emitter follower. Calculate worst- dissipation transistor zener. What the percentage zener the – condition ? Compare your previous circuit.
2.6:Design a +10V regulated supply for load currents from 0V to 100mA; the input voltage is +20V to +25V. Allow at least 10 mA zener current under all (worst-case) conditions. What power rating must the zener have?
