XT1861B332MR-G

NATLINEAR · DC-DC Converters · SOT-23-3L

XT1861B332MR-G from NATLINEAR, in a SOT-23-3L. 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 GND power_in Ground / reference return (接地端). Connect to system ground.
2 LX passive Switch node (开关). Connects to the external boost inductor between VIN and the internal power switch / synchronous rectifier. Rated 1000 mA maximum switch current, 6.5 V absolute maximum.
3 VOUT power_out Regulated boost output (输出端), factory-set to 3.3 V ±2.5% (suffix '33'). Also serves as the IC supply once the output is above the input. Bypass with a 22 µF ceramic capacitor to GND. 6.5 V absolute maximum.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: NATLINEAR datasheet (13 pp, sha256 e936a8c07359ec38, retrieved 2026-08-17, tier: lcsc)
  • Datasheet language: Chinese. Pin names, descriptions, and specs on this page were extracted and translated to English by ds2sf; the linked PDF is the manufacturer original.
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
