HE2210M533R

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

HE2210M533R 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 pin. Accepts 3.0V to 50V (30V recommended max). Bypass to GND with a 1µF (or larger) ceramic capacitor placed close to the device.
2 GND power_in Device ground reference. Connect to the system ground plane with a wide copper trace to minimize noise and improve thermal performance.
3 CE input Chip enable / EN input. Logic-high (VIH ≥ 1.0V at VIN=5V) turns the regulator on; logic-low (VIL ≤ 0.4V) disables the output and drops quiescent current below 0.1µA. Do not leave floating.
4 GND power_in Second ground pin (SOT23-5 pinout shows GND on the bottom-center position). Tie to the same ground plane as pin 2.
5 VOUT power_out Regulated 3.3V output pin (±2% accuracy). Sources up to 400mA. Requires a 10µF ceramic output capacitor (X5R/X7R) placed close to the pin for stability and transient response.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
he2210m533r.step 85 KB You want the bare part, or you mark your own boards.
he2210m533r-etched.step 2.2 MB You want the part with HE2210M533R already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 544 faces against 102 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.

Provenance

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

  • Datasheet: HEERMICR datasheet (10 pp, sha256 97c90148ca9fd8ee, 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).
