Is there a KiCad symbol and footprint for the LD39150DT33-R?
Yes. The symbol is Regulator_Linear:LD39150DT33 and the footprint Package_TO_SOT_SMD:TO-252-3_TabPin2, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the LD39150DT33-R?
DPAK, with 3 pins. Its footprint is drawn on this page.
Where is the LD39150DT33-R datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the LD39150DT33-R?
JLCPCB lists it as part C155559, with 4,451 in stock; the sellers' links on this page open their listings.
What can replace the LD39150DT33-R?
Parts like it in the library: the LM1084RS-3.3 by HTC Korea TAEJIN Tech, the AP1084D33G by Diodes Incorporated, the SPX1587AR-L-3-3/TR by SIPEX and the LM1084S-3.3/TR by HGSEMI. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the LD39150DT33-R?
8 boards in 7 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
