TLV74033PDBVR

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

TLV74033PDBVR 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, 1.4V to 5.5V. Requires a 1µF or larger ceramic input capacitor placed close to the device for best transient response and low input impedance.
2 GND power_in Ground reference pin. Must be connected to the board ground plane.
3 EN input Active-high enable input. Drive high (≥1.0V) to enable the regulator; drive low (≤0.4V) to disable. Do not float - tie to IN if unused. Enable pin current typically 10nA.
4 NC unconnected No internal connection. Connect to ground for best thermal performance or leave floating.
5 OUT power_out Regulated 3.3V output, up to 300mA. Requires a 1µF or greater ceramic output capacitor (0.5µF minimum effective capacitance) to ground for stability, placed as close to the pin as possible.

CAD (KiCad official)

  • Symbol: TLV74033PDBVR
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: tlv74033pdbvr-etched.step / tlv74033pdbvr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tlv74033pdbvr.step / tlv74033pdbvr.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
tlv74033pdbvr.step 85 KB You want the bare part, or you mark your own boards.
tlv74033pdbvr-etched.step 2.1 MB You want the part with TLV74033PDBVR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 538 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 (35 pp, sha256 647bd73d02c1ee3e, retrieved 2026-08-17, tier: lcsc)
  • 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).
