Design a diode voltage regulator to supply 1.5 V to a 1.5-k load. Use two diodes specified to have a 0.7-V drop at a current of 1 mA. The diodes are to be connected to a +5-V supplythrough a resistorR. Specifythe value forR. Whatis 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 1 k? To 750 ? To 500 ? (Hint: Use the small-signal diode model to calculate all changes in output voltage.)
