TPS3106K33DBVR 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	RSTVDD	output	Active-low reset output (open-drain). Logic level at RSTVDD depends only on the voltage at VDD and the status of MR. Requires an external pull-up resistor.
2	GND	power_in	Ground reference for the device.
3	MR	input	Active-low manual-reset input. Pull low to force a reset; RSTVDD/RSTSENSE remain low as long as MR is low and for the time-out period (typ 130 ms) after MR goes high. Has an internal ~100 kΩ pull-up; leave unconnected or tie to VDD if unused.
4	SENSE	input	Secondary voltage-monitor input. A reset is asserted on RSTSENSE when the voltage at SENSE falls below the internal 0.551-V threshold (VIT-(S)). Connect to VDD if unused. Typically driven from a resistor divider on the monitored rail.
5	RSTSENSE	output	Active-low reset output (open-drain). Logic level at RSTSENSE depends only on the voltage at SENSE and the status of MR. Requires an external pull-up resistor.
6	VDD	power_in	Supply voltage input, 0.9 V to 3.6 V recommended (4 V absolute max). Powers the device and is the monitored primary rail; a 0.1 µF ceramic bypass capacitor close to the pin is recommended.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`tps3106k33dbvr.step`	97 KB	You want the bare part, or you mark your own boards.
`tps3106k33dbvr-etched.step`	2.9 MB	You want the part with `TPS3106K33DBVR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 691 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.
