One of the most versatile components around, the LM317 Voltage Regulator allows you to power your circuit with voltages ranging from 2.5V to 15V. Try all all of those higher-voltage circuits you’ve been wanting to experiment with! Another great application is simulating voltage sag like an older battery (great for guitar pedals).

Hi ,
What will be the input voltage required for this circuit ?
is the output amps too variable ?
