Basic Low voltage Regulator

Basic Low voltage Regulator:

Basic Low voltage Regulator (Vo = 2 to 7 volts)

The resistor, Rsc is connected between CL and CS pins. The current limit transistor remains non-conductive unless drops across Rsc is 0.6 V (equal to VBE drop). The value of Rsc can be found out by following equation

Ilimit can be selected as 1.2 to 1.5 times the maximum load circuit. Potential divider made up of R1 and R2 is connected between Vref and non-inverting terminals.
