MD7150 from Shanghai Mingda Microelectronics, 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 / common return for the regulator. Connect to system ground with a low-impedance trace; place the output capacitor return close to this pin.
2 VDD power_in Unregulated supply input (VIN). Operating range up to 18 V absolute maximum. Bypass with a >=1.0 uF input capacitor (CIN) close to the pin.
3 VOUT power_out Regulated 5.0 V (+/-3%) output, up to 30 mA. Requires a >=2.2 uF tantalum (or >=10 uF aluminum-electrolytic) output capacitor for loop stability; low-ESR ceramics may need a 0.5-5 ohm series resistor. Do not let VOUT exceed VIN+0.3 V (parasitic body diode in the pass FET).

CAD (KiCad official)

  • Symbol: MD7150
  • Footprint: Package_TO_SOT_SMD:SOT-23-3
  • 3D model: SOT-23-3L (KiCad packages3D, STEP)
  • 3D model files: md7150-etched.step / md7150-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); md7150.step / md7150.glb are the bare package body.

Provenance

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

  • Datasheet: Shanghai Mingda Microelectronics datasheet (12 pp, sha256 a3ed5d5344bdc5d5, 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).
