pinmap.json pin map: the package TAB (symbol pin 4, OUTPUT) is pad 2, not a fourth pad - the footprint name says so.

tlv1117-33cdcyr.lbr rebuild the library on adom-lbr 2.32.0. The published copy was built by 2.18.0, which imported every KiCad roundrect and oval pad as a SQUARE EAGLE smd; this carries the real pad shape across (0 -> 4 rounded pads) and stops dropping geometry drawn on KiCad User.N layers. Attributes, connects, pads and the pin-1 marker are gated against decreasing and are unchanged. · Ray 1mo ago

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223

TLV1117-33CDCYR from Texas Instruments, in a SOT-223. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 ADJ/GND power_in Ground pin for fixed-voltage variants (TLV1117-33 = 3.3-V fixed). On the adjustable TLV1117 this pin is the ADJ feedback input for the external resistor divider; on fixed-output devices such as the -33 it functions as the device ground reference.
2 OUTPUT power_out Regulated 3.3-V output. Supplies up to 800 mA. Requires an output capacitor for stability; place close to the pin.
3 INPUT power_in Unregulated input voltage pin. For the TLV1117-33 the recommended V_IN range is 4.7 V to 15 V (absolute maximum 16 V). Bypass with a capacitor close to the pin.
4 OUTPUT power_out SOT-223 thermal tab, internally connected to OUTPUT (pin 2). Solder to a copper pour for heat sinking and connect to the OUTPUT net.
