LP5907MFX-3.3

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

LP5907MFX-3.3 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. A minimum 1-µF low-ESR ceramic capacitor should be connected from this pin to GND.
2 GND power_in Common ground. All voltages on the device are referenced to this pin.
3 EN input Enable input. A high level (>VIH = 1.2 V) enables the regulator; a low level (<VIL = 0.4 V) shuts down the regulator and discharges VOUT to GND through an internal ~230-Ω pull-down. An internal 1-MΩ pull-down to GND holds the regulator off by default.
4 NC unconnected No internal electrical connection. May be left floating or tied to any potential.
5 OUT power_out Regulated 3.3-V output, up to 250 mA. Connect a minimum 1-µF low-ESR ceramic capacitor from this pin to GND. An internal ~230-Ω pull-down discharges VOUT to GND when the regulator is disabled (VEN low).

Two STEP files. Same geometry, different body top:

File Size Use it when
lp5907mfx-3-3.step 85 KB You want the bare part, or you mark your own boards.
lp5907mfx-3-3-etched.step 2.1 MB You want the part with LP5907MFX-3.3 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 517 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 (34 pp, sha256 b45948d0449ab80b, 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).
