HE9073A30M5R

HEERMICR · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

HE9073A30M5R from HEERMICR, in a SOT-23-5. 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 Unregulated input supply. Operating range 2.0V to 7.0V (absolute max VSS-0.3 to +9.0V). Bypass with ≥4.7µF ceramic CIN to GND close to the pin.
2 GND power_in Device ground / reference return. Common ground for VIN, VOUT and CE.
3 CE input Chip Enable / ON-OFF logic input. VIH ≥ 1.2V enables the regulator; VIL ≤ 0.4V shuts it down (ISD ≤ 0.1µA). Absolute max VON/OFF = VSS-0.3 to VIN+0.3V. Do not leave floating; tie to VIN for always-on.
4 NC unconnected No internal connection. May be left floating or tied to GND for mechanical robustness.
5 VOUT power_out Regulated output, fixed 3.0V ±1% (HE9073A30 variant), up to 500mA continuous with 550mA current-limit. Requires ≥4.7µF ceramic COUT to GND for stability.

CAD (KiCad official)

  • Symbol: HE9073A30M5R
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: he9073a30m5r-etched.step / he9073a30m5r-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); he9073a30m5r.step / he9073a30m5r.glb are the bare package body.

Provenance

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

  • Datasheet: HEERMICR datasheet (12 pp, sha256 27a01576a32d0f6f, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
