HE2240A36HMR

HEERMICR · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-3

HE2240A36HMR from HEERMICR, in a SOT-23-3. 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. Should be tied to a low-impedance ground plane; input and output capacitor grounds should return here with wide, short traces.
2 VOUT power_out Regulated 3.6V output (Vset0.98 to Vset1.02, IOUT up to 250mA). Requires a 10µF X7R/X5R ceramic capacitor to GND placed close to the pin for stability.
3 VIN power_in Unregulated supply input, 3.0V to 40V absolute max. Bypass with a 10µF ceramic capacitor to GND placed close to the pin.

  • 3D model files: he2240a36hmr-etched.step / he2240a36hmr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); he2240a36hmr.step / he2240a36hmr.glb are the bare package body.

Provenance

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

  • Datasheet: HEERMICR datasheet (9 pp, sha256 30afcc83266a65aa, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
