TPS22919DCKR from Texas Instruments, in a SC-70-6. 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	IN	power_in	Switch input. Load switch source supply, 1.6 V to 5.5 V (abs max 6 V). Bypass with a ceramic capacitor close to the pin.
2	GND	power_in	Device ground reference.
3	ON	input	Active-high switch enable control input. VIH ≥ 1 V, VIL ≤ 0.35 V, abs max 6 V. Contains a smart pull-down (~530 kΩ) that keeps ON low until deliberately driven high; do not leave floating in normal operation.
4	NC	unconnected	No connect. Leave floating.
5	QOD	output	Quick Output Discharge pin. Internal ~24 Ω discharge path to GND when the switch is off. Tie directly to VOUT to use the internal RPD, add an external resistor between VOUT and QOD to adjust fall time, or leave floating to disable QOD. Abs max 6 V.
6	VOUT	power_out	Switch output. Connected to IN through the internal N-channel MOSFET (RON ≈ 90 mΩ at 3.6 V) when ON is high. Supports up to 1.5 A continuous with controlled slew-rate turn-on.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`tps22919dckr.step`	99 KB	You want the bare part, or you mark your own boards.
`tps22919dckr-etched.step`	2.5 MB	You want the part with `TPS22919DCKR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 590 faces against 117 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.
