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.

Add to Watch list. A k ohm or so will control it, and not upset the calibration too much.

Description Postage and payments. When the power supply is started, the input to the jumps to 70 volts or so.

I did a quick look on Digikey and the 1 watt ones I saw were all 9 mm. Not a complete recovery, so this luxeon will be used for testing.

Back to home page Return to top. Fairchid has a 2″x2″x1″ heat sink with a 60mm fan blowing on it. Perhaps a large cap from ADJ pin to ground would help. The failure mode could be anything from latching in over voltage mode pass transistor locked off to being permantly open to fusing the input pin to the other two pins. They only can supply 5 amps though. You’re covered by the eBay Money Back Guarantee if you receive an item that is not as described in the listing.

Those are metal film resistors. The time now is Seller assumes all responsibility for this listing. United States working days: Fairchild LM dies, takes other parts with it The big resistors on the left look like metal oxide to me. 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.

Eventually at board rev time, I used a discrete regulator and never heard from it again. This I’ve seen a fair bit on LMs in a product I supported many years ago.

This would cause very high current spikes through a load like a Luxeon. I assumed that the rate of heat dissipation would require them all to be of the same size.

Perhaps you can post the circuit so we can take a critical look. Faircchild the acrylic cap would no longer fit, I re-sealed it with some normal clear epoxy. If the item comes direct from a manufacturer, it may be delivered in non-retail packaging, such as a plain or unprinted box or plastic bag.
