Product Description

The linear voltage regulator LM317 voltage regulator module can output a regulated DC voltage.

The output voltage range of LM317 is 1.2V to 35V, and the maximum load current is 1.5A.

LM317 has built-in overload protection, safe zone protection and other protection circuits. Usually LM317 does not require external capacitors, and using output capacitors can change the transient response. You can also connect the adjustment terminal to a programmable voltage to achieve programmable power output.

When the module is used, the input voltage and output voltage need to have a certain voltage difference, generally more than 2V.

This upgraded version comes with a rectifier bridge, 3A1000V withstand voltage, and supports AC/DC dual input.

Module size: 47mm*20mm

Input voltage (withstand voltage): 35V (DC maximum 35V, AC maximum 20V)

Output voltage: 1.2V-33V adjustable

Load regulation rate: 25mV

Quiescent current: 1mA

Input-output voltage difference: 2V

Peak current: 1.5A

Product Applications 

1) Adjustable three-terminal voltage regulator module, which can replace all three-break voltage regulator modules such as 7806, 7824, etc.

2) Car-mounted voltage regulator, just connect the input end of this module to the car cigarette lighter for power supply, you can adjust the potentiometer, and the output voltage can be adjusted between 1.25V-30V to power your mobile phone, MP3, MP4, PSP charging and many other devices, which is very simple and convenient.

3) System pre-stage power supply, when you are doing a project and the input power supply voltage is lower than the voltage you need (1.25V-30V), then you can choose our module.

DIY power supply, monitoring power supply, experimental power supply, camera power supply, car power supply, communication equipment power supply can all be used

Product FAQ

FAQ:

Can I adjust the voltage by myself?

Answer: Yes, the blue one is the adjustable potentiometer, no-load debugging, use a multimeter to measure the range you want and it will be OK.

Does this power module have short-circuit protection? Will it burn out if I accidentally short-circuit the input when using it?

Answer: The input will not be short-circuited. The module has a rectifier bridge input without distinguishing between positive and negative poles, and can be AC or DC
