LP3964EMP-2.5

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223-5

LP3964EMP-2.5 from Texas Instruments, in a SOT-223-5. 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 SD input Shutdown input; the datasheet gives an operating range of −0.3 V to VIN + 0.3 V, and SD must be pulled high through a 10-kΩ pullup in the typical application.
2 IN power_in Input supply, operating from 2.5 V to 7 V; the minimum operating input is VOUT(NOM) + VDROPOUT or 2.5 V, whichever is greater.
3 GND power_in Ground pin for the regulator.
4 OUT power_out Regulated output voltage, specified for up to 0.8 A DC and short-circuit protected.
5 SENSE/AD input Remote sense pin (output adjust pin on the adjustable version) that improves regulation at remote loads; the maximum voltage on SENSE is VOUT + 0.3 V.

CAD (KiCad official)

  • Symbol: LP3964EMP-2.5
  • Footprint: Package_TO_SOT_SMD:SOT-223-5
  • 3D model: SOT-223-5, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 1.45 mm nominal SOT height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
  • 3D model files: lp3964emp-2-5-etched.step / lp3964emp-2-5-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lp3964emp-2-5.step / lp3964emp-2-5.glb are the bare package body.
