LM317 DC-DC Voltage Regulator

Description The 220V DIY LM317 regulator is a nice little module to get the power you want from the power you have. Specifications: Product name: lm317 adjustable regulated power supply module Product size: 53.0 mm * 22.0 mm * 14.80 mm Yan color: blue product weight: 16.53 g (packaging) 1. Output current: 1.5 A (minimum), 2.2 A (typical) 2. The input and output voltage difference (VI – VO) : 40 VDC (maximum) 3. Adjustable output voltage range: 1.2 ~ 37 v 4. Working temperature: 55 ° C to 150 ° C 5. : output current 1.5 A 6. Input voltage: 4.2 ~ 40 V 7. The working temperature: 0 ° C to 125 ° C 8. Characteristic frequency: 100 (MHz) Using the tutorial: Input mode: VIN input level, GND input cathode Output: VOUT is output level, GND output is negative Adjust way: first right after the input power supply (4.5 V -) between 40 V, output voltage with a multimeter monitoring and tuning potentiometer (general chronological booster, the backward turn step-down) Notes from our engineers: The voltage should be set at the loaded condition ITO output impedance.
