HE2021A36HMR

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

HE2021A36HMR from HEERMICR, in a SOT-23. 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 Device ground reference. Connect to single-point ground with input/output bypass capacitor returns (10µF typical each) tied here.
2 VOUT power_out Regulated output, +3.6V nominal (3.564V min / 3.636V max at IOUT=10mA), sourcing up to 200mA. Recommended 10µF output bypass capacitor to GND for stability.
3 VIN power_in Unregulated supply input, operating range up to 35V absolute maximum. Requires VIN ≥ 4.6V for regulation of the 3.6V output; recommended 10µF input bypass capacitor to GND.

  • 3D model files: he2021a36hmr-etched.step / he2021a36hmr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); he2021a36hmr.step / he2021a36hmr.glb are the bare package body.

Provenance

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

  • Datasheet: HEERMICR datasheet (9 pp, sha256 8d7e2c2e64e2ae10, 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).
