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.

Those little ones must get extra hot when dissipating 1 watt. I did a quick look on Digikey and the 1 watt ones I saw were all 9 mm. We only accept payment through Paypal. Those are metal film resistors.

It’s a selectable version of the basic 3 terminal regulator in current source configuration. And the carbon film is no doubt carbon dioxide. This would cause very high current spikes through a load like a Luxeon.
Not sure if it’ll work or not, but it’ll be fun to try. Perhaps you can post the circuit so we can take a critical look.

In my application, that shouldn’t have been an issue. I assumed that the rate of heat dissipation would require them all to be of the same size. gairchild
The short version is to fix it, I used a 39V Zener around the to limit the differential and ramped the input voltage so the caps had a chance to charge. Fairchid post to United States See details. Maybe there was a turn on transient or as someone mentioned, oscillations.
