Re: FS: LM1117 Linear Driver - 1.3A Fixed Yup ... ceramic pig.

Re: FS: LM1117 Linear Driver - 1.3A Fixed Extremely Limited Edition drivers available: 501mA - 7 Available 444mA - 5 Available (May work with 1 high quality IMR/LowR li-ion cell for Red diodes) *Still have 20x1.8A and 24x1.3-1.6A Drivers available. No order limits.

Awesome! ... glad your diode is not dead. Sounds like the driver might be ok, Ill still check it to make sure and try to get it back in the mail the same day I get it.

Re: FS: LM1117 Linear Driver - 1.3A Fixed Yokatta! oO{1.9!?}

Its about a $20 premium to have good IMR cells that wont blow up on you and not have to wait a month for the stuff to arrive from China. There are other cheaper chargers @ lighthound, but the one I linked to can handle all the different cells sizes. Here is a cheaper one...

Cells: AW IMR16340 550 mAh IMR CR123 size LiMN Rechargeable Lithium Battery Charger: Ultrafire WF-188 Charger for 14500 / 17500 / 18500 / 18650 / RCR123 3.7 volt Lithium Battery Charger Theoretically I would not expect more than 40 minutes of run time on one charge, but I've never actually...

Re: FS: LM1117 Linear Driver - 1.3A Fixed Will do.

I deleted it because what I had posted was wrong. I though V- and GND were still common, and they are not.

Wooohooo! Look what the nice folks @ Gentec sent me. :)

Re: FS: LM1117 Linear Driver - 1.3A Fixed I don't make much at all, not nearly enough to cover the time I spend building them. Laying down 100's of tiny solder paste blobs with a syringe is a pain in the you know where. Ill be converting an IR toaster oven into an Arduino controlled reflow oven...

Re: FS: LM1117 Linear Driver - 1.3A Fixed For those of you that wanted more than the limit, the initial wave has died down enough to lift the restriction. I have 28 LM1117(1.3A) and 16 LD1085(1.8A) left in stock. I have 108 LM1117 and 72 LD1085 PCBs coming this week. :)

Re: FS: LM1117 Linear Driver - 1.3A Fixed The IC has internal protection for heat and over-current, so it should have been ok. If its not putting anything out it could be a bad IC. Send it back to me and Ill check it out. PM sent.

Re: FS: LM1117 Linear Driver - 1.3A Fixed Yes you could do that. You could also put like a 10K across the dummy load's LD+/-, this prevents leaving the cap charged. Just have to account for the additional current draw, but @ 10kOhm its going to be less than 1mA.

Re: FS: LM1117 Linear Driver - 1.3A Fixed Yup always discharge the cap ... they may be small but they are 10uf's and they hold enough of a charge to zap these diodes without a problem.

Re: FS: LM1117 Linear Driver - 1.3A Fixed Do you have a dummy load?

What is you Vin? What is you dummy load Vfw? Also nominal Vref for this chip is 1.24V, but that doesn't explain the problem here nor does it make a significant difference in the calculation(539mA). Its either starving for voltage or going into thermal shutdown ... you may not have enough...

:bumpit: 4 short weeks away. All your lase are belong to us!

I did a test a few days ago with a LM1117 driver setup for 430mA with a 3V dummy load @ single li-ion voltages with a 2A(Max) bench PSU. I imagine this driver will have similar response: 4.2V = 430mA 4.1V = 420mA 4.0V = 410mA 3.9V = 400mA 3.8V = 380mA 3.7V = 360mA, really starts dropping after...

Re: FS: LM1117 Linear Driver - 1.3A Fixed I have a fixed value buck/boost driver design but the parts are too expensive to make any significant quantities and its difficult to build by hand. I would have to charge a lot more than what other buck/boost drivers go for. :( Bluuray is correct, it...
