New LM317 DC-DC Linear Converter Buck Step Down Low Ripple Module Power Supply Product parameters: 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) Package is installed, a single module electrostatic bag packing materials: FR4 + electronic components Product performance: 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 The maximum output current, output current = 3 / (input voltage, output voltage) Input voltage: 4.5 V - 40 V (limit our measured at up to 40 V), 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) Warm prompt: in regulating voltage, the voltage required in no load getting attention please Statement: this module output power the load capacity of the module itself also the levels before after the power supply and load, and other factors;The following data measured results by professional equipment, does not consider other factors. Power supply module is a kind of electronic components, please no electronic information clear knowledge professionals consider buying again.
