Skema Regulator 3 volt menggunakan IC LM317

Skema Regulator 3 volt menggunakan IC LM317 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.
