HE2028A33GR

HEERMICR · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-252

HE2028A33GR from HEERMICR, in a TO-252. 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 3.0V to 50V (recommended max 30V for continuous use). Decouple with a 10µF ceramic capacitor placed close to the pin.
2 VOUT power_out Regulated 3.3V output, ±2% accuracy, up to 800mA. Requires a 10µF X7R/X5R ceramic output capacitor placed close to the pin for stability. Dropout is 360mV at 100mA.
3 GND power_in Ground reference and thermal pad (exposed tab). Connect to a wide copper pour for thermal dissipation; the tab conducts heat away from the die (θJA = 150°C/W for TO-252-3L).

CAD (KiCad official)

  • Symbol: HE2028A33GR
  • Footprint: Package_TO_SOT_SMD:TO-252-2
  • 3D model: TO-252 (KiCad packages3D, STEP)
  • 3D model files: he2028a33gr-etched.step / he2028a33gr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); he2028a33gr.step / he2028a33gr.glb are the bare package body.

Provenance

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

  • Datasheet: HEERMICR datasheet (9 pp, sha256 d8423fb2deb81247, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
