LP3965EMP-2.5

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

LP3965EMP-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: pull low (0 to 0.2V) to turn the regulator off, and pull high (VIN to VIN-0.3V) for normal operation, with survival limits of -0.3V to VIN+0.3V and a typical turn-off delay of 20 µs at 1.5A load.
2 VIN power_in Input supply pin, operating from 2.5V to 7.0V (survival -0.3V to +7.5V), where the minimum VIN is the greater of VOUT(NOM)+VDROPOUT or 2.5V.
3 VOUT power_out Regulated output pin, supplying up to 1.5A DC with output voltage tolerance of ±1.5% at 25°C and ±3.0% over line, load and temperature.
4 SENSE/ADJ input Remote sense pin for the fixed-voltage LP3965 that improves regulation at the load, with the voltage on this pin limited to VOUT+0.3V.
5 GND power_in Ground pin, which carries the ground pin current of typically 5 mA at 1.5A load and 15 µA typical in shutdown mode.

CAD (KiCad official)

  • Symbol: LP3965EMP-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: lp3965emp-2-5-etched.step / lp3965emp-2-5-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lp3965emp-2-5.step / lp3965emp-2-5.glb are the bare package body.
