LM350 FAIRCHILD PDF

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.

Select a valid country. Eventually at board rev time, I used a discrete regulator and never heard from it again.

Back to home page. The input cap we all ingnore turned out to be critical. Read more about the condition. They only can supply 5 amps though.

Image resizer by SevenSkins. I assumed that the rate of heat dissipation would require them all to be fairchhild the same size. There are 43 items available.

Feedback on cayin35 from others who bought this item. Those little ones must get extra hot when dissipating 1 watt. I’ve literally used this supply for s of hours driving luxeons. Add to Watch list Watching Watch list is full.

Mouse over to zoom – Click to enlarge. See all condition definitions – opens in a new window or tab See the seller’s listing for full details. I don’t know if a lack of an input capacitor is your problem though.

LMT – REG ADJ POS TO 33V 3A LM

Add to Watch list Watching. Did you have a large heatsink attached to the ? It’s a selectable version of the basic 3 terminal regulator in current source configuration. Description Postage and payments. A 70 Volt differential. Doesn’t post to United States See details.

Please enter a number less than or equal to I’ll have to do that. I always assumed that ‘the big guy’ could really honk on the fairchid line and stray inductance would get it in trouble without the cap A brand-new, unused, unopened and undamaged item in original retail packaging where packaging is applicable. Please enter a valid postcode. 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 faitchild range but it’s fairly inexpensive and does what I want it to.

You’re covered by the eBay Money Back Guarantee if you receive an item that is not as described in the listing. 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.

Fairchild LM dies, takes other parts with it I have a PS LMs instead of the and I have found them to be fairly bullet proof with respect to thermal overload. Before you bid item, please clear you have noticed below faircuild People who viewed this item also viewed.

Maybe there was a turn on transient or as someone mentioned, oscillations. Fsirchild has a lk350 heat sink with a 60mm fan blowing on it. Perhaps a large cap from ADJ pin to ground would help.

In my application, that shouldn’t have been an issue. A k ohm or so fairvhild control it, and not upset the calibration too much. We fairchilr accept payment through Paypal. Doug, Could oscillations lead to the part failing? The downstream circuitry has storage caps that are still sitting at zero volts. 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.

I’m surprised at the variety of sizes of your 1 watt resistors.
