Question Ptr080100 and 08060wvd

[Bakuku]

Ok so yesterday I made a 1.9v regulator using the Ptr080100 and a 08060 and both dont work. They start heating up and producr smoke :/ .
The coil on the 08060 even fell off :/

I know I hooked it up correctly and even checked the datasheets on both. But no go.

My benchpower is working because other regulators work fine...

Please help!

maybe a pic of your connections can help a little to identify the problem

Here you go.

Something tells me if smoke comes out of it and components start falling off, you did not hook it up correctly.

They're probably toast.

For the first picture, I assume you had ground to black, power to brown/orange (can't tell for sure which it is), white for output, and the resistor connected to ground?
And for the second picture, white for power in, brown for ground, yellow for output?

Also, you were feeding a voltage below 14v right?

Yes correct and voltages were kept below 10v.

I burned 2 regs with the same symptoms. the diagnostic: bad wired because I used a wrong reg diagram.

Could you link me a correct PTR08060WVD datasheet? I've seen some where the pins were reversed as well...

i recomend to follow this guide, because there is a similar in another forum but the pins are wrong

That's the same as the datasheets from the official TI website, I checked that with him, he followed that. Do either of the caps show up as a short for continuity?

Can someone PM me this incorrect diagram? I want to take a look.

On the 08060 yes. The 08100 no. Both don't work.
