TCR2EF33

TOSHIBA LM CT · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TSOT-25

TCR2EF33 from TOSHIBA LM CT, in a TSOT-25. 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 1.5 V to 5.5 V (absolute max 6.0 V). Bypass to GND with CIN >= 0.1 µF (ceramic acceptable).
2 GND power_in Device ground reference and return for VIN, VOUT, and CONTROL. Connect to system ground plane.
3 CONTROL input Enable input. HIGH (VCT >= 1.0 V, up to 5.5 V) turns the regulator ON; LOW (VCT <= 0.4 V) or OPEN turns it OFF (internal pull-down between CONTROL and GND). Standby current IB(OFF) ~0.1 µA typ. at VCT = 0 V.
4 NC unconnected No internal connection. May be left floating; recommended to leave unconnected or tie to GND per PCB layout preference.
5 VOUT power_out Regulated 3.3 V output (TCR2EF33). Sources up to 200 mA. Requires COUT >= 1.0 µF ceramic to GND for stability. Includes auto-discharge when regulator is turned off via CONTROL.

Ordering variants

Same part, different packaging or reel option.

CAD (KiCad official)

  • Symbol: TCR2EF33
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: TSOT-25 (KiCad packages3D, STEP)
  • 3D model files: tcr2ef33-etched.step / tcr2ef33-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tcr2ef33.step / tcr2ef33.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
tcr2ef33.step 85 KB You want the bare part, or you mark your own boards.
tcr2ef33-etched.step 1.7 MB You want the part with TCR2EF33 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 406 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: TOSHIBA LM CT datasheet (17 pp, sha256 7ba2a7e4e81e13f9, retrieved 2026-08-17, tier: manufacturer)
  • 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).
