Note: DIY KIT needs to be soldered by yourself
Product description:
The LM317 L337 alone can meet the needs of general equipment, but for higher accuracy and better thermal stability, adding TL431 as a reference voltage regulator has increased by 1-2 levels, with lower noise and lower ripple. The cost is not too high. Of course, good capacitors, high-speed tubes, BI are adjustable, and the price is up by 1 point. The filter is 6800UF 35V gold adjustable NOVER American BI Philips high speed diode and so on.
Product parameters:
PCB size: 85X56MM
Input voltage: AC6V-AC25V
Output voltage: DC 3V3-DC25V
Maximum output current: 1.5A
LM317 337 is a very good ON brand, better than general 317, TL431 is originally from TI.
