10 Power Supply Recommendations

The LM317L device is designed to operate from an input voltage supply range between 2.5 V to 32 V greater than the output voltage. If the device is more than six inches from the input filter capacitors, an input bypass capacitor, 0.1 µF or greater, of any type is needed for stability.
