Brand new and high quality.
Module introduction:
Name: Adjustable linear regulator
Output current: 1.5A (minimum), 2.2A (typical)
Input and output voltage difference (VI-VO): 40Vdc (max)
Output adjustable voltage range: 1.2 ~ 37V
Operating temperature: -55 ° C to + 150 ° C
Current output: 1.5A
Voltage input: 4.2 ~ 40 V
Operating temperature: 0 ° C to 125 ° C
Characteristic frequency: 100 (MHz)
Module size: 35.6 (mm) x16.8 (mm)
Input mode: VIN input positive level, GND input negative pole
Output mode: VOUT output positive level, GND output negative
Maximum output current: maximum output current = 3 / (input voltage - output voltage)
Buyers need to know because it is linear, so the efficiency is not very high, in order to improve efficiency, it is best to input and output 3V pressure difference. But the maximum input and output voltage difference is not more than 30V, namely: input - ≤ 30V, otherwise it is easy to burn the module.

Because it is linear step-down DC-DC circuit, so the input voltage needs more than 3V output voltage difference in order to ensure the stability of the output voltage.
Input voltage: 40V-4.5V (Our measured maximum limit of up to 40V)

Adjustment method: the first input power (40-4.5) and then use a multimeter to monitor the output voltage and adjust the potentiometer (generally turn up the pressure in turn, reverse the buck)

Warm Tip: When adjusting the voltage, be sure to adjust the required voltage when not loaded

Use:
1) adjustable three-terminal regulator module, can replace 7805,7806,7809,7812,7824 and all other three-way regulator module
1). Car power supply, only need to connect the module input on the car cigarette lighter power supply, you can adjust the potentiometer,
The output voltage can be in 1.25V-30V let you adjust your phone, MP3, MP4, PSP charge and many other equipment power supply, very simple and convenient Oh.
3). For your electronic equipment power supply, when your equipment needs 1.25-60V power supply, but now you only hands 12V or 24V battery-powered, with our module can directly buck 1.25-30V, to solve your troubles The
4). The system power supply, when you do a project when the input voltage is less than you need the voltage (1.25V-30V) when you choose our module will be your best choice.
