LP2980IM5X-3.3 from Texas Instruments, 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	IN	power_in	Input supply voltage. Operating range 2.1 V to 16 V (absolute max 16 V). A 1-µF input bypass capacitor is recommended close to this pin.
2	GND	power_in	Common ground (device substrate). Return for both the regulator quiescent current and the load current.
3	ON/OFF	input	Active-high enable input. Drive above logic-high threshold to enable the regulator; pull below 0.18 V to place the device in shutdown (<1 µA quiescent). Do not leave floating.
4	N/C	unconnected	DO NOT CONNECT. Reserved for post-package test and calibration of VOUT accuracy. Must be left floating; do not tie to ground or any potential. Aggressive continuity testing on this pin can disturb the factory trim and push VOUT out of tolerance.
5	OUT	power_out	Regulated 3.3-V output, 50 mA rated (150 mA peak typ). Requires a minimum 1-µF output capacitor (2.2 µF typical) for stability; typical dropout 120 mV at 50 mA.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`lp2980im5x-3-3.step`	85 KB	You want the bare part, or you mark your own boards.
`lp2980im5x-3-3-etched.step`	2.5 MB	You want the part with `LP2980IM5X-3.3` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 615 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.
