10pcs LM317 Adjustable Voltage Regulator Power Supply LM317T DC-DC Converter Buck Step Down Circuit Board Linear Regulator
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)
