TPS27081ADDCR from Texas Instruments, in a SOT-23-6. 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	R2	output	Source terminal of internal NMOS (Q2). Connect to system GND directly, or through an external slew-rate control resistor R2 to shape the ON/OFF transition and limit inrush current on CL.
2	VOUT	power_out	Drain terminal of the power PFET (Q1); switched output to the load. Pins 2 and 3 are internally the same VOUT node; connect a slew-control capacitor CL between VOUT and R1/C1 (pin 6) if needed.
3	VOUT	power_out	Drain terminal of the power PFET (Q1); switched output to the load. Tie pins 2 and 3 together on the board to share the full 3-A continuous / 9.5-A pulsed drain current.
4	VIN	power_in	Source terminal of the power PFET (Q1). Supply input, 1.2 V to 8 V (abs max 8 V vs R2). Connect a pull-up resistor R1 between VIN and the R1/C1 gate node (pin 6).
5	ON/OFF	input	Active-high enable input for the load switch; VIH >= 1 V, VIL <= 0.3 V, abs max 8 V. When driven by a high-impedance driver, connect an external pull-down resistor to GND to define the off state.
6	R1/C1	passive	Gate terminal of the power PFET (Q1) and drain of the control NMOS (Q2). Connect the R1 pull-up resistor from VIN to this pin, and (optionally) a slew-shaping capacitor C1 between this pin and VOUT to control turn-on/turn-off dV/dt and inrush current.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`tps27081addcr.step`	97 KB	You want the bare part, or you mark your own boards.
`tps27081addcr-etched.step`	2.4 MB	You want the part with `TPS27081ADDCR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 588 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.
