Design a diode voltage regulator to supply 1.5 V to a 150-
Chapter 4, Problem 4.54(choose chapter or problem)
Design a diode voltage regulator to supply 1.5 V to a 150- 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 voltage when the load is disconnected? What change results if the load resistance is reduced to 100 ? To 75 ? To 50 ? (Hint: Use the smallsignal diode model to calculate all changes in ouput voltage.)
