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.

10PCS Voltage Regulator IC NSC/FAIRCHILD TO LM LMT /NOPB NEW | eBay
That’s the one that took 48W for a few seconds – it was glowing and smoking! Fairchild LM dies, takes other parts with it. This doesnt explain why the LM device failed however.
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.

Fairchild LM dies, takes other parts with it I thought those voltage regulators ICs were fool proof. Bookmarks Bookmarks Digg del. Since the luxeon is dead anyways, I’m going to try to pop the dome off and see about soldering fairhild bond wire back together. And the carbon film is no doubt carbon dioxide.

I started to test the supply its self by hooking it directly to a low value current sense resistor 0. Fairchild LM dies, takes other parts with it Hi evan, Sorry to hear about that.
Normally, this causes 0. Fairchild LM dies, ln350 other parts with it I’ve got the old part bags those came from – lemme dig em up. The short version is to fix it, I used a 39V Zener around the to limit the differential and firchild the input voltage so the caps had a chance to charge.

Fairchild LM dies, takes other parts with it Doug, Thanks for the suggestion.
You’re covered by the eBay Money Back Guarantee if you receive an item that is not as described in the listing. Those metal films are probably metal oxide now. 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 Do you plan a mass burial? And the voltage can l3m50 set all the way up to 30 volts, so they aren’t completely fool proof. Fairchild LM dies, takes other parts faorchild it Doug, Could oscillations lead to the part failing?
A 70 Volt differential. If the pot wiper contact is dirty it could cause it to open intermittently when it’s being adjusted.
Those little ones must get extra hot when dissipating 1 watt. I’m surprised at the variety of sizes of your 1 watt resistors. For blowing up Luxeons, and doing other interesting things, I recommend one of these power supplies.

Build anything, call it an amplifier and it will oscillate. Maybe there was a turn on transient or as someone mentioned, oscillations. How does this fit with the topic?

The downstream circuitry has storage caps that are still sitting at zero volts. For some reason, after a computer restart I can now see your schematic.
