2011年8月23日 · Hello, I'm a first time poster, occasional lurker. Done some maths on the LM317,350 and 338 to drive LEDs, was wondering how close to the ball park I am or if I'm …

2012年1月29日 · The LM338 is the same with 5A as minimum, 8A to 12A as "typical" and they don't say how much is maximum, maybe 15A. You need an accurate circuit to regulate the …

2020年5月30日 · LM317 and LM338 are easy to use and pretty straightforward devices for voltage regulation. LM338 is said to be able to supply 5A and LM317 more than 1A current. …

2018年6月8日 · You did not post the schematic and resistor values that are producing trouble. The resistors for an LM338 are the same as for an LM317. The datasheet for the LM338 …
