ITEM NAME:LM317 Adjustable Regulated Rectifier Filter Power Supply Board Module M&E 100% Brand New and High Quality LM317 as a good regulator, with high stability, high temperature, high linearity and other characteristics, the output voltage range up to 1.25V ~ 30V continuously adjustable, the maximum operating current of more than 1A (using a large radiator or Active cooling measures). The board with a rectifier bridge, and equipped with 50V 2200uF filter capacitor, can effectively reduce the output ripple and interference. LM317 linear regulator module, the input DC voltage can be regulated output. LM317 built-in overload protection, safe area protection and other protection circuit. Normally the LM317 does not require an external capacitor, and the output capacitor can change the transient response. Voltage difference between the input and output must be more than 3V DC Input Voltage: 5 ~ 35V AC Input Voltage: 6 ~ 25V DC Output Voltage: 1.25 ~ 30V adjustable Output current range: maximum continuous operating current
