ME301CMG

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

ME301CMG from MICRONE, 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 Vss power_in Ground reference pin. Must be tied to a solid ground plane; if Vss is not well grounded the internal zero reference shifts with switching current and operation becomes unstable.
2 Lx output Switch node - drain of the internal NMOS boost switch. Connects to the junction of the external inductor and Schottky rectifier (e.g. 1N5817/1N5819). Absolute max VLX = 6.5V; max switch current ILX = 600mA; switch-on current typical ~100mA (max 160mA at VLX=0.4V, Vout=Vout*0.95).
3 Vout power_out Regulated boost output and internal-circuit supply / output-voltage sense pin. Factory-trimmed to 3.0V (±2.5%) for the ME301C variant. Bypass with ≥10µF tantalum (47µF/16V recommended) plus 0.1µF ceramic close to the pin. Also powers the internal control circuitry.

Provenance

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

  • Datasheet: MICRONE datasheet (None pp, sha256 c6c98bd13fa393f3, 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.
