TL780: Wrong PCB lib

Max Guan

Part Number: TL780

Just a reminder on the TL780 footprint pin assignment for KTT package on TI website, that pin1 and pin3 (input and output) are mismatched (swapped) against datasheet symbol.

(I was able to see the error on Altium Designer symbol)

Hello Max,

Thank you for bringing this to our attention, we'll take a closer look.

TL780 KTT package is an EOL device, if possible, I recommend switching to UA7805CKTTR it is a P2P replacement and the CAD/CAE symbols are in accordance with the datasheet.

Best,

Thank you for the proposal. I'll look into the datasheet to see if it fits.

Hello Max,

No problem. A quick solution for using TL780 will be to rename the pinout of the device on Altium and/or add net labels. Please let me know if further assistance is needed.

Best,
