Title： LM317 LM337 Adjustable Regulated Power Supply Board / Kit DC Voltage Product name: Regulated Power Supply Board Product model: YS-LM317-LM337 Working voltage: DC: +-1.25V－37V Load Current: 1.5A Size: 103x45mm Output Current: 1.5A Base Board Thickness: 2mm Copper Foil Thickness: 75U Option： Please choose complete board or Kit board before ordering! Description: LM317 / lm337 is a three terminal adjustable voltage regulator IC of National Semiconductor Corporation of the United States. It is an excellent series integrated voltage regulator widely used. Specification The output voltage range of LM317 / lm337 is 1.2V to 37V, and the maximum load current is 1.5A. It is very simple to use, only two external resistors to set the output voltage. In addition, its linear regulation rate and load regulation rate are better than the standard fixed voltage regulator. LM317 / lm337 has built-in overload protection, safety zone protection and other protection circuits. This product adopts double-sided high-grade PCB (base plate is 2mm, copper foil thickness is 75u, not 50U), imported new on LM317 / 337 high-precision voltage regulator IC, imported Bi adjustable resistor. If you want it 12V, it will never give 12.1v. The assembly of heating element is beautiful and reasonable. DC output voltage + - 1.25v-37v adjustable, output current: 1.5A.
