RT9013-33GB-MS

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

RT9013-33GB-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 Regulator power input. Accepts up to 5.5 V recommended (7 V abs max). A 1 uF to 10 uF ceramic input capacitor to GND is recommended.
2 GND power_in Device ground / return for input and output currents. Also the reference return for the CE input (internal 1 MΩ pull-down between CE and GND).
3 CE input Chip enable (active high). Drive above VCE (recommended >= 1.1 V) to enable the regulator; drive to 0 V to shut down (ICEL < 1 uA). Internal 1 MΩ resistor to GND, so the pin must not be left floating.
4 NC unconnected No internal connection. Leave floating or tie to GND for improved layout.
5 VOUT power_out Regulated output. Fixed 3.3 V for the -33GB-MS option; delivers up to 500 mA. A 1 uF to 10 uF ceramic output capacitor to GND is required for stability.

Two STEP files. Same geometry, different body top:

File Size Use it when
rt9013-33gb-ms.step 85 KB You want the bare part, or you mark your own boards.
rt9013-33gb-ms-etched.step 2.7 MB You want the part with RT9013-33GB-MS already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 655 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 (9 pp, sha256 4db96a23f249c60c, 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).
