LP5907MFX-1.8

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

LP5907MFX-1.8 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 voltage supply (2.2 V to 5.5 V). Connect a 1-µF ceramic capacitor at this input. Absolute max 6 V.
2 GND power_in Common ground. All voltages are referenced to this pin.
3 EN input Enable input. A low voltage (<VIL) turns the regulator off and discharges the output pin to GND through an internal 230-Ω pulldown resistor. A high voltage (>VIH) enables the regulator output. Internal 1-MΩ pulldown holds the regulator off by default. Absolute max 6 V.
4 N/C unconnected No internal electrical connection.
5 OUT power_out Regulated 1.8-V output (up to 250 mA). Connect a minimum 1-µF low-ESR ceramic capacitor to this pin. Connect this output to the load circuit. An internal 230-Ω (typical) pulldown resistor prevents charge remaining on VOUT when the regulator is in shutdown mode (VEN low).

CAD (KiCad official)

  • Symbol: LP5907MFX-1.8
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: lp5907mfx-1-8-etched.step / lp5907mfx-1-8-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lp5907mfx-1-8.step / lp5907mfx-1-8.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
lp5907mfx-1-8.step 85 KB You want the bare part, or you mark your own boards.
lp5907mfx-1-8-etched.step 1.9 MB You want the part with LP5907MFX-1.8 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 487 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 (46 pp, sha256 eb1c24bcba3fa5ce, 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).
