LP5907MFX-2.85

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

LP5907MFX-2.85 from Texas Instruments, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 IN input Input voltage supply. Connect a 1µF capacitor at this input.
2 GND power_in Common ground.
3 EN input Enable input. A low voltage (< VIL) on this pin turns the regulator off and discharges the output pin to GND through an internal 230Ω pulldown resistor. A high voltage (> VIH) on this pin enables the regulator output. This pin has an internal 1MΩ pulldown resistor to hold the regulator off by default.
4 N/C unconnected No internal electrical connection.
5 OUT output Regulated output voltage. Connect a minimum 1µF low-ESR capacitor to this pin. Connect this output to the load circuit. An internal 230Ω (typical) pulldown resistor prevents a charge remaining on VOUT when the regulator is in shutdown mode (VEN low).

CAD (KiCad official)

  • Symbol: LP5907MFX-2.85
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • Annotated 3D hero: lp5907mfx-2-85-hero.glb (dashed pad outlines, silkscreen with pin 1, signal names; the adom-hero standard) is what the viewer shows. Downloads and EDA use the clean model, lp5907mfx-2-85-etched.glb.
  • 3D model files: lp5907mfx-2-85-etched.step / lp5907mfx-2-85-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lp5907mfx-2-85.step / lp5907mfx-2-85.glb are the bare package body.
