Product description:

LM317 as a good regulator, with high stability, high temperature, high linearity and other characteristics, the output voltage range up to 1.25V ~ 37V 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 with a 3300uF filter capacitor, can effectively reduce the output ripple and interference.
Input voltage range: AC5V-20V
Output voltage range: DC1.25V-30V (continuously adjustable)
Output current range: maximum continuous operating current <600mA (pressure difference of not more than 10V), the pressure exceeds 10V, please ensure that the output current <400mA
Operating temperature range: 0 ° C-100 ° C (to prevent over-temperature damage, can increase their own heat or use other active cooling method)
Linear regulator LM317 regulator module, the input DC voltage can be regulated output.
LM317 output voltage range is 1.2V to 35V, the maximum load current of 1.5A.
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.
This programmable voltage enables programmable power output.
Module input voltage and output voltage need to have a certain pressure difference is generally more than 2V.
The upgrade comes with rectifier bridge, 3A1000V voltage, support 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: 25mV
Quiescent current: 1mA
Input and output differential pressure: 2V
Peak current: 1.5A

Package included:

1PC LM317 Adjustable Regulated Power Supply Board
