IC LM317T
New Voltage regulatorsA voltage regulator with a stabilized adjustable output voltage. It has an integrated current limiter in case of a short circuit. It is truly difficult to list all the applications it is suitable for, but here are a few: programmable logic controllers, battery bank charging, inverter welding machines, brushed and brushless motor control, stepper motors, etc. Vin = 1.25V to 37V, Vout = 3V to 40V, Current - 1.5A+.
