LN2266PB2MR-G from NATLINEAR, in a SOT-23-6. 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	CE	input	Chip enable input. Drive high to enable the converter; drive low (< 0.4V) to shut the device down (IOFF typ. 0.01uA). CE shutdown threshold is typ. 0.8V (0.4-1.2V) referenced to VDD=3.3V. In the '-B' option this pin also drives the external MOSFET expansion path.
2	NC	unconnected	No connect. Leave floating or tie to GND.
3	GND	power_in	Device ground return. Connect to the system ground plane with a low-impedance path close to the input/output capacitors.
4	LX	power_out	Switching node / rectifier terminal. Drain of the internal 2.5A N-MOS power switch; connects to the boost inductor and Schottky rectifier (e.g. 1N5819) anode. Absolute max VLX = Vss+5.5V; internal RDS(on) ~0.18Ω.
5	VDD	power_in	Supply input to the control circuitry. Operating range 2V to 5.2V (absolute max 5.5V). Bypass with a 10uF ceramic capacitor close to the pin. Startup guaranteed from VIN as low as 0.9V (at IL=1mA) via the LX/inductor path.
6	FB	input	Feedback input to the error amplifier. Regulates to Vref = 1.25V (±2% for the '2' accuracy option). Set VOUT with an external resistor divider: VOUT = 1.25V * (1 + R1/R2). Programmable output range 2V to 5.2V.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`ln2266pb2mr-g.step`	97 KB	You want the bare part, or you mark your own boards.
`ln2266pb2mr-g-etched.step`	2.4 MB	You want the part with `LN2266PB2MR-G` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 595 faces against 117 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.
