AP2210N-5.0TRG1 from Diodes Incorporated, in a SOT-23. 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	VIN	power_in	Supply input voltage. Recommended operating range 2.5V to 13.2V (abs max 15V). Bypass to GND with a 1.0µF ceramic capacitor close to the pin.
2	GND	power_in	Device ground reference. Return path for both quiescent (ground pin current, typ 100µA at IOUT=100µA) and load current return through the input/output capacitors.
3	EN	input	Enable input, CMOS/TTL compatible. Logic high (VIH ≥ 2.0V) enables the regulator; logic low (VIL ≤ 0.4V, shutdown at ≤0.18V) forces shutdown (ISTD ≤ 1µA). Abs max VEN = 15V.
4	BYP	passive	Bypass pin for low-noise operation on the fixed-output (5.0V) version. Connect a ~100pF ceramic capacitor from BYP to GND to reduce reference noise. On the ADJ variant this pin is the feedback ADJ input instead; on this fixed 5.0V part it is the BYP node.
5	VOUT	power_out	Regulated 5.0V output, up to 300mA. Requires a 2.2µF ceramic output capacitor to GND for stability. Line/load regulation typ 1.5mV/1mV; dropout typ 250mV at 300mA.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`ap2210n-5-0trg1.step`	59 KB	You want the bare part, or you mark your own boards.
`ap2210n-5-0trg1-etched.step`	2.3 MB	You want the part with `AP2210N-5.0TRG1` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 561 faces against 69 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.
