Desired D.C. Output : 10 V
Load Variation: 0.3 kilo-ohms - 10 kilo-ohms
Ripple Factor: Less than 0.1% for 2 kilo-ohms load
Load Regulation: Better than 3 mV for a 1 mA change in load current
Line Regulation: Better than 3 mV for a 1V change in line voltage
Design Restrictions:
Capacitor values should not exceed 50 micro Farads. If a bigger capacitor is needed, use an Op amp based capacitor simulator.
Output Stage:
First at the output stage use a Zener shunt regulator and then replace the Zener shunt regulator with an appropriate IC voltage regulator.
