TLV313IDCKR from UMW, in a SC-70-5. 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	Op-amp output. Rail-to-rail output stage that can swing close to V+ and V-.
2	V-	power_in	Negative (lowest) power supply. Connect to ground for single-supply operation or to the negative rail for split supplies. Total supply (V+ - V-) range is 1.8 V to 5.5 V.
3	+IN	input	Noninverting input. Rail-to-rail input; common-mode range extends slightly beyond both supply rails. Input bias current is typically 1 pA.
4	-IN	input	Inverting input. Rail-to-rail input; common-mode range extends slightly beyond both supply rails. Input bias current is typically 1 pA.
5	V+	power_in	Positive (highest) power supply. Operating supply range 1.8 V to 5.5 V referenced to V-. Bypass to V- with a 0.1 µF ceramic capacitor placed close to the pin.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`tlv313idckr.step`	87 KB	You want the bare part, or you mark your own boards.
`tlv313idckr-etched.step`	1.8 MB	You want the part with `TLV313IDCKR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 465 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.
