TPS3808G33DBVR 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	RESET	output	Active-low, open-drain RESET output. Driven to a low-impedance state whenever SENSE is below V_IT (3.07 V typ for the G33 option) or MR is low; released to high-Z after the user-programmed reset delay expires. Requires an external pull-up resistor of 10 kΩ to 1 MΩ; the pin may be pulled above V_DD (up to 6.5 V). I_RESET max = 5 mA (absolute max).
2	GND	power_in	Device ground reference.
3	MR	input	Active-low manual reset input. Driving MR low (V_IL ≤ 0.3·V_DD) asserts RESET; MR must return above V_IH (≥ 0.7·V_DD) for RESET to release after the delay. Internally pulled up to V_DD through a ~90 kΩ resistor (70-110 kΩ), so the pin may be left unconnected if unused. Minimum input pulse width: 1 μs.
4	CT	passive	Reset delay-time programming pin. Leave open for the fixed 20 ms delay, tie to V_DD (through 40 kΩ-200 kΩ) for the fixed 300 ms delay, or connect a ground-referenced capacitor ≥ 100 pF to program a user delay from 1.25 ms (100 pF) to 10 s (180 nF). Absolute-max voltage: −0.3 V to V_DD + 0.3 V.
5	SENSE	input	Voltage-monitor input. Connected internally to a precision comparator (0.5% typ threshold accuracy for V_IT ≤ 3.3 V); when the SENSE voltage drops below V_IT (3.07 V typ on the G33 option), RESET is asserted. Input current is 1.7 μA typ at V_SENSE = 6.5 V. A 1 nF-10 nF bypass to GND is recommended to reduce transient sensitivity.
6	VDD	power_in	Supply voltage input. Operating range 1.65 V to 6.5 V (1.7-6.5 V over full −40 °C to +125 °C range); I_DD = 2.4 μA typ at V_DD = 3.3 V. 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
`tps3808g33dbvr.step`	97 KB	You want the bare part, or you mark your own boards.
`tps3808g33dbvr-etched.step`	3.3 MB	You want the part with `TPS3808G33DBVR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 770 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.
