xc6219b122mr.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 -> 5 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

XC6219B122MR

TECH PUBLIC · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

XC6219B122MR from TECH PUBLIC, in a SOT-23-5. 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	VIN	power_in	Supply power input. Operating range 1.6V to 5.5V (absolute max 6V). Bypass with a 1uF ceramic capacitor to GND.
2	GND	power_in	Device ground reference.
3	CE	input	Chip enable input. Drive high to enable the regulator; drive low (Vce=0V) to enter shutdown mode (~1uA standby current).
4	NC	unconnected	No internal connection. May be left floating or tied to GND.
5	VOUT	power_out	Regulated voltage output, 1.2V (XC6219B122MR variant), 300mA typical output current. Bypass with a 1uF ceramic capacitor to GND.

XC6219B122MR

CAD (KiCad official)

Symbol: XC6219B122MR
Footprint: Package_TO_SOT_SMD:SOT-23-5
3D model: SOT-23-5 (KiCad packages3D, STEP)
3D model files: xc6219b122mr-etched.step / xc6219b122mr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); xc6219b122mr.step / xc6219b122mr.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`xc6219b122mr.step`	85 KB	You want the bare part, or you mark your own boards.
`xc6219b122mr-etched.step`	2.3 MB	You want the part with `XC6219B122MR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 565 faces against 102 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
