HT7833

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

HT7833 from TECH PUBLIC, 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. Operating range 1.2V to 5.5V (absolute max -0.3V to +6.5V). Bypass with a 1µF to 10µF ceramic capacitor to GND.
2 GND power_in Device ground reference. Ground current is only 2µA typical at no load.
3 CE input Chip Enable (active-high). Drive above VIH=2V to enable the regulator; drive below VIL=0.6V to place the device in shutdown (ISD ~10nA typical, 0.5µA max). EN input current is 10nA typical at VEN=5V.
4 NC unconnected No internal connection. May be left floating or tied to GND.
5 OUT power_out Regulated output. Fixed 3.3V ±2% at ILOAD=0.1mA; delivers up to 500mA with 0.32V typical dropout at 500mA. Current limit 500mA min / 800mA typical. Requires a 1µF to 10µF ceramic or tantalum output capacitor to GND for stability.

Two STEP files. Same geometry, different body top:

File Size Use it when
ht7833.step 85 KB You want the bare part, or you mark your own boards.
ht7833-etched.step 1.4 MB You want the part with HT7833 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 340 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: TECH PUBLIC datasheet (10 pp, sha256 fdebd5bb2fcc5e9a, 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).
