TLV73333PDBVR

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

TLV73333PDBVR from Texas Instruments, 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 IN power_in Input supply pin, 1.4 V to 5.5 V. A small input capacitor (typ. 1 µF) from IN to GND is recommended for best transient response.
2 GND power_in Ground reference for the regulator. All voltages are referenced to this pin.
3 EN input Enable pin. Drive EN > 0.9 V to turn on the regulator; drive EN < 0.35 V to put the LDO into shutdown. EN range is 0 to VIN; EN pin current is ~0.01 µA at VEN = 5.5 V.
4 NC unconnected No internal connection. May be left floating or tied to GND.
5 OUT power_out Regulated 3.3 V output, up to 300 mA. Output capacitor is not required for stability; a small 1 µF ceramic cap from OUT to GND is recommended for best transient response. An internal ~120 Ω active pull-down discharges the output when the device is disabled.

CAD (KiCad official)

  • Symbol: TLV73333PDBVR
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: tlv73333pdbvr-etched.step / tlv73333pdbvr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tlv73333pdbvr.step / tlv73333pdbvr.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
tlv73333pdbvr.step 85 KB You want the bare part, or you mark your own boards.
tlv73333pdbvr-etched.step 2.3 MB You want the part with TLV73333PDBVR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 573 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: Texas Instruments datasheet (36 pp, sha256 fd300ef78c941eeb, retrieved 2026-08-17, tier: manufacturer)
  • Datasheet language: Chinese. Pin names, descriptions, and specs on this page were extracted and translated to English by ds2sf; the linked PDF is the manufacturer original.
  • 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).
