SP6205EM5-L from MaxLinear, 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	VIN	power_in	Power supply input, 2.7V to 5.5V operating range (absolute max -2V to +6.0V). Recommend 2.2µF ceramic input capacitor (CIN) to ground close to the pin.
2	GND	power_in	Ground terminal. Ground pin current is the regulator quiescent plus ground current (typ. 5µA quiescent, ~350µA at 500mA load).
3	EN	input	Enable / Shutdown input. Logic high (≥1.6V) enables the regulator; logic low (≤0.4V) puts the part into shutdown (~0.01µA typical). Absolute max -2V to +6V; operating range 0V to 5.5V. Do not leave floating.
4	ADJ	input	Adjustable regulator feedback input (adjustable output voltage option, applies to SP6205EM5-L). Connect to the midpoint of an external resistive divider between VOUT and GND; VOUT = 1.25V × (1 + R1/R2). Internal reference is 1.25V (typ.).
5	VOUT	power_out	Regulator output voltage. Rated 500mA continuous (SP6205). Requires a 2.2µF ceramic output capacitor (COUT) to GND for stability; unconditionally stable with 2.2µF ceramic. Absolute max -0.6V to VIN + 1V.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`sp6205em5-l.step`	85 KB	You want the bare part, or you mark your own boards.
`sp6205em5-l-etched.step`	2.1 MB	You want the part with `SP6205EM5-L` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 503 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.
