MD85E36QC3 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 Power input pin. Operating range 2.2V to 40V (absolute max 45V). Requires a 2.2uF or larger ceramic input capacitor placed close to the pin.
2 GND power_in Ground reference for the regulator.
3 EN input Enable pin (active high). Drive high (V_ENH: 1.5V to 40V) to enable the regulator; drive low (V_ENL: 0 to 0.6V) to place the device into low-current shutdown (<100nA typical at VIN=40V). Do not leave floating.
4 NC unconnected No internal connection. Leave floating or tie to GND.
5 VOUT power_out Regulated output voltage pin, fixed at 3.6V (±2% accuracy) for the MD8536 option. Delivers up to 300mA continuous. Requires a 2.2uF or larger ceramic output capacitor placed close to the pin. VOUT must not exceed VIN+0.3V (parasitic body diode to VIN).

  • 3D model: SOT-23-5L (KiCad packages3D, STEP)
  • 3D model files: md85e36qc3-etched.step / md85e36qc3-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); md85e36qc3.step / md85e36qc3.glb are the bare package body.

Provenance

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

  • Datasheet: Shanghai Mingda Microelectronics datasheet (13 pp, sha256 b57d90f008c009b2, retrieved 2026-08-17, tier: lcsc)
  • 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).
