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 (VCEH >= 1.2V) to enable the regulator; drive low (VCEL <= 0.9V) to place the device in shutdown (typical standby current 0uA, max 1uA at VIN=5V). Absolute max -0.3V to VIN+0.3V. |+| 2 | GND | power_in | Ground return for the device and power stage. |+| 3 | LX | output | Switching node - output of the internal power MOSFET stage. Connect to the external inductor (typ. 2.2uH). Absolute max current +/-1500mA; abs max voltage -0.3V to VIN+0.3V. Peak current limit typ. 1.2A. |+| 4 | VIN | power_in | Power supply input, 1.8V to 5.5V operating range (absolute max 6.5V). Bypass with a 4.7uF ceramic capacitor close to the pin. |+| 5 | FB | input | Output voltage feedback input. Connect to the resistor divider from VOUT; internal reference is 0.6V typ. (0.59-0.61V). Input bias current +/-50nA max. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | NATLINEAR |+| Package | SOT-23-5L |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++- `XT3406AFMR-GAFMR`+- `XT3406AFMR-GAFML`++## CAD (KiCad official)++- Symbol: `XT3406AFMR-G`+- Footprint: `Package_TO_SOT_SMD:SOT-23-5`+- 3D model: SOT-23-5L (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [NATLINEAR datasheet](docs/xt3406afmr-g-datasheet.pdf) (7 pp, sha256 `84eba0563afcd9fe`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
