Check for Samples: LM, LMN, LMA. In addition to higher −40°C ≤ TJ ≤ +°C, and the LM is rated for 0°C handled. ≤ TJ ≤ +°C. The LM is an adjustable 3-terminal positive voltage . FAIRCHILD’S PRODUCTS ARE NOT AUTHORIZED FOR USE AS CRITICAL COMPONENTS IN LIFE. I have a current regulated supply (fed by a 24V power supply) that used to have a Fairchild LM in it. This supply has a set of switches that let.

Seller assumes all responsibility for this listing. If the regulator is only a few inches from its “power supply” a separate capacitor isn’t needed. Not sure if it’ll work or not, but it’ll be fun to try. United States working days: I started to test the supply its self by hooking it directly to a low value current sense resistor 0.

Those little ones must get extra hot when dissipating 1 watt. When the latter happens, the vairchild downstream sometimes gets mad and leaves also. And the carbon film is no doubt carbon dioxide.

Mexico, South America Because of some post and custom reason, we ship item to worldwide but exclude the following countries and area: I did a quick look on Digikey and the 1 watt ones I saw were all 9 mm.


Before you bid item, please clear you have noticed below details: In the cases I had to deal with, stray inductance in the power leads did as all inductors do, had zero DC voltage across it but an AC voltage that went to ground The short version is to fix it, I used a 39V Zener around fairchold to limit the differential and ramped the input voltage so the caps had a chance to charge.

Fairchild LM dies, takes other parts with it Those metal films are probably metal oxide fxirchild. It’s also not such a bad idea to run a switcher ahead of the LM or to keep the voltage just above that which is needed for the device roughly 3v higher than Vout.

Doug, Could oscillations lead to the part failing? Take a look at our Returning an item help page for more details.

I used to work with an EE who was fond of saying ‘all amplifiers oscillate, all oscillators amplify, and my power supplys do both’. Add to Watch list. Have one to sell? I assumed that the rate of heat dissipation would require them fairchiild to be of the same size.

My config has two regulators that are daisy chained CC configured regulator feeds the voltage regulated side – it’s not very efficient and has a limited range but it’s fairly inexpensive and does what I want it to. I also smelled a slight burning electronics smell but couldn’t pinpoint it. Fairchild LM dies, takes other parts with it I did some bypass surgery on the dead luxeon: Maybe there was a turn on transient or as someone mentioned, oscillations.

Those are metal film resistors.
