Description
1、Module description:
LM317 is a three terminal adjustable positive voltage regulator integrated circuit for National Semiconductor Corporation Ns. The output voltage range of LM317 is 1.2V to 37V, and the maximum load current is 1.5A. Its use is very simple, only two external resistors to set the output voltage. In addition its linear adjustment rate and load adjustment rate is also better than the standard fixed voltage regulator. LM317 built-in overload protection, security zone protection and other protective circuit.
2、Function Description:
Wide voltage input, the output voltage can be adjusted, the output voltage can be adjusted through the potentiometer, obviously the output voltage to be lower than the input voltage, so the output voltage of several V, the input voltage to be appropriate.
