HT44-Q

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

HT44-Q from QNH, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 GND power_in Ground pin of the regulator; the output capacitor of greater than 2.2µF must be connected from VOUT to ground.
2 VOUT power_out Regulated 4.4V output (HT44) rated for 100mA minimum output current, needing an output capacitor greater than 2.2µF to ground (tantalum recommended).
3 VIN power_in Supply input with an absolute maximum of -0.3V to +24V, with the input capacitor placed close to the pin.

CAD (KiCad official)

  • Symbol: HT44-Q
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: ht44-q-etched.step / ht44-q-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ht44-q.step / ht44-q.glb are the bare package body.

Provenance

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