5-35VDC or 5-22VAC to 1-34VDC LM317T Adjustable Step Down Linear Regulator Converter Power Supply Module
This LM317T regulator module converts an input DC voltage from 5V to 35V, or an AC input voltage from 5V to 22V, to 5V to 34V DC output voltage, continuously variable by means of the onboard multi-turn potentiometer.
It lets you use those surplus computer and wall plug power supplies as an adjustable source of clean DC power for electronics, radios, and other equipment. Simply connect the power supply input to the input of the regulator, and adjust the regulator's output to your desired voltage using the onboard potentiometer. The large 1000uF input filter capacitor reduces output ripple, noise, and interference, removing most of the "hash" noise created by common switching wall warts and laptop power supplies.
For example, a 19V computer power supply can be used to create a clean, regulated, adjustable DC power source with output from a few volts to about 16V.
The module also features an input rectifier bridge facilitating AC as well as DC input.
Specifications
* This is a step-down regulator, therefore the input voltage must be at least ~2.5V greater than the output voltage.
