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. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | NATLINEAR |+| Package | SOT-23-6 |+| Category | PMIC |+| Pins | 6 |++## Ordering variants++- `LN2266PB2MR-G`+- `LN2266PB2MR-GLN2266PA2MR-G`+- `LN2266PB2MR-GLN2266PB1MR-G`+- `LN2266PB2MR-GLN2266PA1MR-G`+- `LN2266PB2MR-GLN2266P**M*-G`+- `LN2266PB2MR-GLN2266P**P*-G`++## CAD (KiCad official)++- Symbol: `LN2266PB2MR-G`+- Footprint: `Package_TO_SOT_SMD:SOT-23-6`+- 3D model: SOT-23-6 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [NATLINEAR datasheet](docs/ln2266pb2mr-g-datasheet.pdf) (8 pp, sha256 `d10d6fe1e894f9a4`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
