IC723 as a HIGH voltage HIGH Current

An external transistor Q is added in the circuit for high voltage low current regulator to improve its current sourcing capacity.

IC723 as a HIGH voltage HIGH Current:


·           An external transistor Q is added in the circuit for high voltage low current regulator to improve its current sourcing capacity.

 

·           For this circuit the output voltage varies between 7 & 37V.

 

·           Transistor Q increase the current sourcing capacity thus IL(MAX)ia greater than 150mA.

 

·           The output voltage Vo is given by ,
