MD52E30QC3 from Shanghai Mingda Microelectronics, in a SOT-23-5L. 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 VIN power_in Input supply voltage, 2.2V to 7.0V range (absolute max -0.3 to 8V). Requires a 1.0µF or larger input decoupling capacitor.
2 GND power_in Device ground / return. GND current is typically 0.6µA at no load and 210µA at IOUT=500mA.
3 EN input Enable input, active-high (logic-high enables the regulator). VENH ≥ 1.0V enables output; VENL ≤ 0.38V disables. When EN=0, COUT is auto-discharged through an internal ~450Ω resistor and shutdown current drops to ~0.01µA.
4 NC unconnected No internal connection. Leave floating or tie to a convenient net for PCB routing; no electrical function.
5 VOUT power_out Regulated 3.0V output, up to 500mA. Requires a 1.0µF or larger low-ESR ceramic output capacitor. Line regulation 0.05%/V typ, load regulation 50mV typ (1mA-500mA).

  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5L (KiCad packages3D, STEP)
  • 3D model files: md52e30qc3-etched.step / md52e30qc3-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); md52e30qc3.step / md52e30qc3.glb are the bare package body.

Provenance

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

  • Datasheet: Shanghai Mingda Microelectronics datasheet (14 pp, sha256 4168b8cf3e52f15f, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
