Package Include: 1 set LM317 Adjustable Voltage Regulator Step-down module DIY Kit LM317 Kit Descriptions: It is DIY kit,need weld each component together. It can input DC/AC power,but only can output DC. Input DC volt:5V-35V Input AC volt:6V-25V output DC volt:1.25V-30V output circuit:1A(max) minimun dropout voltage of input and output:3V Listing: PCB board x1 KF3.96-2P x1 1N4007 x5 Switch x1 scoket x1 PTC Resettable Fuse x1 50V 407UF electrolytic capacitor x1 104 ceramic capacitor x2 M3*6 screw x1 LM317 x1 heak sink x1 5K adjustable resistor x1 Potentiometer knob x1 2N5551 x1 5.1K resistor x1 220ohm resistor x1 25V 10UF capacitor x1 50V 2200UF capacitor x1 LM317 with LED Features: Adjustable regulator module with LED display. 2A or less can be loaded, AC or DC voltage input. The output voltage is 1.25V-28V DC continuously adjustable, versatile for DC board. Using double adjustment potentiometer to ensure good contact, effectively protect the load. Notice: The minimum differential between input and output is 3V; the input must be higher than the output voltage above 3V to be regulated. Buck, not boost, when input 5V output 1.25-2V, not 6V. Specifications: Input Voltage: DC: 0-30V; AC: 0-22V Output Voltage: DC 1.25-28V Output Current: 2A(Max.)
