2009年1月17日 · The LM317 I noticed got very warm, but not overly hot. I decided on the LM317 to regulate, because the source voltage can be from about 14.x volts when the alternator is …

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. …

2025年1月5日 · I'm sorry, I guess that I wasn't clear enough. I don't need it as a Li Ion battery charger, I want to add a current limit circuit in order to make a lab power supply. my intention …

2008年1月31日 · I agree with Steve about starting out on a switcher. The layout is critical. For your application assuming 9V in and 5V out and 100mA max average current you should be …

2020年2月17日 · A resistor in series with the LM317 input will reduce the voltage, but I don't see a particular need for that here. For example, a 30Ω, 2W resistor in series will reduce the voltage …

2011年8月23日 · LM317 as a current limiter control: Confusing LM317 voltage regulator output: Need help to double check LM317 circuit: curious observation in using LM350/LM317: Help …

2016年1月17日 · The LM317 data sheet specifies the junction-to-ambient thermal resistance, in the TO-220 package, at 19 °C/watt. So if you're dissipating 12W, the internal die temperature …

2025年3月8日 · Hi everyone, I am trying to make a circuit with lm317 to have a constant current. I would like to use it with both a constant voltage generator and a pulsed voltage generator. …

2011年7月28日 · As amazing as it seems I am having trouble locating an alternative Linear Voltage regulator for the LM317 with a Lower Drop Out Voltage and adjustable Output Voltage …

2014年4月11日 · You can parallel two LM317 using "emitter resistors" if you don't mind a slight reduction in voltage regulation. Just put a resistor after the Vout pin, one resistor on each …
