EA8103T5R from Everanalog IC design, 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	RUN	input	Enable / on-off control input. Drive above 1.5V to turn the converter on, drive below 0.4V to turn it off. Absolute maximum input voltage is -0.3V to +7V. Must not be left floating.
2	GND	power_in	Device ground return. Connect to the system ground plane; also serves as the low-side reference for the input and output capacitors and the feedback divider.
3	SWITCH	output	Power switching node output between the internal high-side PMOS and low-side NMOS. Connect to the output inductor (typ. 1uH to 4.7uH). Absolute maximum swing is -0.3V to (VPWR+0.3V); this is a high-current, high dv/dt noise node so keep traces short and wide.
4	PWR	power_in	Power input supply pin, 2.6V to 6V (absolute maximum +7V, OVP threshold ~7V). Bypass with a 10uF X5R/X7R MLCC placed as close to the pin as possible; provides current to the internal high-side PMOS (RDS(ON) ~200mΩ, current limit 1.8-2.4A).
5	FBK	input	Feedback input to the internal error amplifier. Connect a resistor divider from VOUT to FBK to GND to set the output voltage; regulated to VREF = 1.13V (1.107V-1.153V). Leakage current is +/-1uA max. Absolute maximum is -0.3V to +7V.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`ea8103t5r.step`	85 KB	You want the bare part, or you mark your own boards.
`ea8103t5r-etched.step`	1.9 MB	You want the part with `EA8103T5R` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 459 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.
