Features:

Output current: 1.5A (min), 2.2A (typ)
Input/output voltage difference (VI-VO): 40Vdc (max)
Output adjustable voltage range: 1.2~37V
Working temperature: -55℃~+150℃
Current output: 1.5A
Voltage input: 4.2~40V
Operating temperature: 0℃~125℃
Characteristic frequency: 100 (MHz)
Module size: 36mm x 17mm x 22mm
Weight: 16.5g/piece
Input mode: VIN input is positive, GND input is negative
Output mode: VOUT output is positive, GND output is negative
Please note: Please use within 40V! (The input voltage must be at least 3V higher than the output voltage, to ensure the stability of the output voltage.)

You can adjust the voltage you need by yourself.
Adjustment method: Debug under no-load condition, adjust the blue potentiometer, and use a multimeter to measure the required voltage range.

There is no short-circuit protection, so if short-circuit protection is required, connect a self-recovering fuse in series with the input.

Usage range:

1. Three-terminal stabilization module can be adjusted. Can replace all three-break stable modules such as 7805, 7806, 7809, 7812, 7824.

2.The on-board stable power supply can adjust the potential by simply supplying electricity to the input terminal of this module from the car's ignition port. Output voltage can be adjusted between 1.25V-30V. Charge equipment such as mobile phones, MP 3, MP 4, PSP, etc.

3. When powering electrical equipment and equipment requires 1.25-60 V power supply, currently only 12 V or 24 V batteries can provide power. Use this module to directly reduce the pressure from 1.25 V-30 V and solve that problem.

4.The system power supply is lower than the input voltage required (1.25V-30V) when doing a certain project.
