Design a diode voltage regulator to supply 1.5 V to a 150-ohm load. Use two diodes specified to have a 0.7-V drop at a current of 10 mA. The diodes are to be connected to a +5-V supply through a resistor R. Specify the value for R. What is the diode current with the load connected? What is the increase resulting in the output votage when the load is disconnected? What change results if the load resistance is reduced to 100ohms? To 75ohms? To 50ohms?
