RT9193-33GB-MS

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

RT9193-33GB-MS from MSKSEMI, 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. Operating range 1.2 V to 6 V (absolute max 6 V). Bypass to VSS with a 10 uF ceramic capacitor placed close to the pin.
2 VSS power_in Device ground / return for input and output capacitors. Reference for CE logic thresholds.
3 CE input Active-high chip-enable input. VCEH >= 1.6 V (up to VIN) enables the regulator; VCEL <= 0.5 V (down to 0 V) disables it and drops quiescent current to ~1 uA. Input current 0.5 uA max over VCE=0 V to VIN. Do not leave floating.
4 NC unconnected No internal connection. May be left floating or tied to VSS for improved PCB routing/mechanical stability.
5 VOUT power_out Regulated 3.3 V output (3.24 V min / 3.300 V typ / 3.360 V max at Iout=1 mA, Vin=5 V). Delivers up to 300 mA (Vin=4.3 V). Requires a 10 uF ceramic output capacitor to VSS for stability.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
rt9193-33gb-ms.step 85 KB You want the bare part, or you mark your own boards.
rt9193-33gb-ms-etched.step 2.7 MB You want the part with RT9193-33GB-MS already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 654 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: MSKSEMI datasheet (8 pp, sha256 f30db9087e2ca5f2, 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).
