RS7533-1YF3

Jiangsu RUNIC Tech · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-3

RS7533-1YF3 from Jiangsu RUNIC Tech, 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 Ground reference pin. All device voltages are specified with respect to this pin.
2 VOUT power_out Regulated 3.3V output pin. Delivers up to 150mA. Recommended output capacitor range is 1µF to 10µF for stability.
3 VIN power_in Regulator input supply pin. Accepts up to 36V (absolute max 40V). At least a 1µF supply bypass capacitor is recommended close to the pin.

CAD (KiCad official)

  • Symbol: RS7533-1YF3
  • Footprint: Package_TO_SOT_SMD:SOT-23-3
  • 3D model: SOT-23-3 (KiCad packages3D, STEP)
  • 3D model files: rs7533-1yf3-etched.step / rs7533-1yf3-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); rs7533-1yf3.step / rs7533-1yf3.glb are the bare package body.

File Size Use it when
rs7533-1yf3.step 59 KB You want the bare part, or you mark your own boards.
rs7533-1yf3-etched.step 2.0 MB You want the part with RS7533-1YF3 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 477 faces against 69 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: Jiangsu RUNIC Tech datasheet (11 pp, sha256 818bd81e05d2139f, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
