IC723 as a HIGH voltage LOW Current

This circuit is capable of supplying a regulated output voltage between the range of 7 to 37 volts with a maximum load current of 150 mA.

IC723 as a HIGH voltage LOW Current:


 

·           This circuit is capable of supplying a regulated output voltage between the range of 7 to 37 volts with a maximum load current of 150 mA.

 

·           The Non – inverting terminal is now connected to Vref through resistance R3.

 

·           The value of R1 & R2 are adjusted in order to get a voltage of Vref at the inverting terminal at the desired output.

 

 

·           Rsc is connected between CL & Cs terminals as before & it provides the short circuit current limiting


      The value of resistors R3 is given by ,
