HE9073A28M5R

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

HE9073A28M5R 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 Regulator input supply pin. Operating range 2.0V-7.0V (absolute max 9.0V). Bypass to GND with a ≥4.7µF ceramic capacitor close to the pin.
2 GND power_in Device ground reference. Return path for input, output and quiescent currents.
3 CE input Chip Enable (active-high). Logic-high (VIH ≥ 1.2V) turns the regulator on; logic-low (VIL ≤ 0.4V) puts the device into shutdown (ISD ≤ 0.1µA). Do not leave floating; tie to VIN for always-on operation.
4 NC unconnected No internal connection. Leave floating or tie to GND on the PCB.
5 VOUT power_out Regulated 2.8V output. Delivers ≥500mA typical (550mA current limit). Bypass to GND with a ≥4.7µF ceramic output capacitor for stability.

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.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
