Not as high a max supply voltage as the TCA0372, but that's a big boy slew rate and output current for the price: <https://www.mouser.com/ProductDetail/Richtek/RT9147ZQW?qs=amGC7iS6iy%252B8qrugDBrQag%3D%3D>

I hope the thermal limit actually works. It doesn't on TCA0372.

It’s about 12 MHz GBW, vs 1.4ish for the TCA0372 or the old Fairchild L272, or a pitiful 350 kHz for the ST version. It has a power pad, and costs 67 cents in hundreds. (The others have gone way up in price.) LCSC doesn’t have any, which is a bit inconvenient.
