This is based circuit of the LM317 adjustable voltage regulator with a maximum output of 3V/1.5A. The output voltage
depends on the Pin 1 (pin ADJ) of IC LM317 or R1 and R2 values, so the
circuit Can be modified to use with a maximum output of greater than 3V.
while for the maximum output current is related to the package
options.In this circuit, LM317T, Which is capable of transferring up to
1.5A, is used.

When
we adjust the R2 to 1.2K then the output becomes nearly 1.56V which is a
typical battery voltage level that can be used in development projects.
R6 sets the current of the current source so it operates as a zero adjustmend resistor. When the resistor R2 is set to zero, adjust R6 to see zero voltage at the output. R5 protects the transistor BCW33. Red LED is used as a light indicator.

The LM117 is a series of adjustable 3-terminal positive voltage regulators is capable of supplying in excess of 1.5A over a 1.2V to 37V output range. They are exceptionally easy to use and require only two external resistors to set the output voltage. Further, both line and load regulation are better than standard fixed regulators.
