COS6001TR from COSINE, in a SOT23-5. 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	OUT	output	Amplifier output. Rail-to-rail output stage swings to within ~1mV of each supply rail with RL=100kΩ (8mV at 10kΩ, 40mV at 2kΩ). Short-circuit source/sink current typically 21/22mA.
2	-Vs	power_in	Negative supply rail (or ground for single-supply operation). Operating supply range +Vs to -Vs is 1.8V to 5.5V; for dual supplies use ±0.9V to ±2.75V. Bypass to ground with 0.1µF ceramic placed close to the pin.
3	+IN	input	Non-inverting (positive) input of the amplifier. Rail-to-rail common-mode input range extends from -Vs -0.1V to +Vs +0.1V (typical). Input bias current ±2.5pA typical; inputs are diode-clamped to the supplies.
4	-IN	input	Inverting (negative) input of the amplifier. Voltage range -Vs -0.3V to +Vs +0.3V; input signals swinging more than 0.5V beyond a rail must be current-limited to ≤10mA.
5	+Vs	power_in	Positive supply rail. Operating range 1.8V to 5.5V (single-supply). Bypass with a 0.1µF ceramic capacitor placed as close to the pin as possible; a 2.2µF tantalum may be added for improved performance.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`cos6001tr.step`	85 KB	You want the bare part, or you mark your own boards.
`cos6001tr-etched.step`	2.0 MB	You want the part with `COS6001TR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 470 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.
