Module description:Linear regulator LM317 voltage Regulator module, can be input DC voltage regulator output.The output voltage range of LM317 is 1.2V to 35V, the maximum load current is 1.5A. LM317 built-in overload protection, security zone protection and other protection circuits. Usually the LM317 does not require an external capacitor, and the output capacitor is used to change the transient response. Can also be adjusted to the end of a programmable voltage, to achieve programmable power output. The input voltage and output voltage need to have a certain pressure difference for 2V or above when using the module.This upgrade with the Rectifier bridge, 3a1000v withstand pressure, support AC/DC dual input. Module size: 47mm*20mm input voltage (withstand voltage): 35V (max DC 35V, ac max 20V); Output voltage: 1.2v-33v Adjustable load adjustment rate: 25mV; Static Current: 1mA; Input and output pressure difference: 2V Peak Current: 1.5A Package includes:1pc
