Output Current: 1.5A (min), 2.2A (typ)
Input-output voltage differential (VI-VO): 40Vdc (max)
Adjustable output voltage range: 1.2 ~ 37V
Operating temperature: -55 Celsius ~ +150 Celsius
Current output: 1.5A
Voltage Input: 4.2 ~ 40 V
Operating temperature: 0 Celsius ~ 125 Celsius
Characteristic frequency: 100MHz
Module size: 35.6 mm x16.8 mm
Input Method: VIN input is positive, GND Input Negative
Output Method: VOUT output positive, GND output negative
Maximum output current = 3/(input voltage - output voltage)
Note:
1.Because it is a linear step-down DC-DC circuit, the input voltage needs to be more than 3V higher than the output voltage to ensure the stability of the output voltage.
2.Adjustment method: first connect the input power supply correctly (between 40-4.5), then use a multimeter to monitor the output voltage and adjust the potentiometer (usually clockwise to boost, reverse clockwise to buck)
3.The module is linear, so the efficiency will not be very high. In order to improve the efficiency, there needs to be a voltage difference of 3V between the input and output. But the maximum voltage difference between the input and output should not exceed 30V, that is: the input-output is less than or equal to 30V, otherwise It is easy to burn out the module.
4. If you need short-circuit protection, please connect a self-recovery fuse in series with the input terminal.
Package includes：
5xLM317 Adjustable Regulator Power Supply Module
2x50cm/19.68inch 24AWG Cable
