LP3965EMP-1.8

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

LP3965EMP-1.8 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: pulling it low (VSD ≤ 0.2V) turns the regulator off with about 15µA typical quiescent current, and its operating range is −0.3V to VIN+0.3V.
2 VIN power_in Input supply pin, specified for 2.5V to 7.0V operation, with a survival limit of −0.3V to +7.5V.
3 VOUT power_out Regulated output pin, with a survival limit of −0.3V to +7.5V; the output PMOS diode is forward biased if VOUT is forced above VIN.
4 SENSE/ADJ input On the LP3965 fixed-output versions this is a remote sense pin that improves regulation at the load, and on the ADJ version it is the output adjust pin; its maximum voltage is VOUT+0.3V.
5 GND power_in Ground pin for the regulator.

CAD (KiCad official)

  • Symbol: LP3965EMP-1.8
  • 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-1-8-etched.step / lp3965emp-1-8-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lp3965emp-1-8.step / lp3965emp-1-8.glb are the bare package body.
