LP3852EMP-3.3

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

LP3852EMP-3.3 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 specifies a shutdown input voltage range of -0.3 V to 7 V and requires it to be pulled high through a 10-kΩ pull-up resistor.
2 IN power_in Input supply; the datasheet specifies a 2.5 V to 7 V input supply range, with the minimum VIN equal to the greater of VOUT(NOM) + VDROPOUT or 2.5 V.
3 OUT power_out Regulated output voltage (3.3 V nominal for the LP3852EMP-3.3 variant), with a maximum DC output current of 1.5 A.
4 ERROR output ERROR flag output that goes low when the output voltage drops 10% below its nominal value; it must be pulled high through a 10-kΩ resistor, or connected to ground if the function is not used.
5 GND power_in Ground reference for the regulator.

CAD (KiCad official)

  • Symbol: LP3852EMP-3.3
  • 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: lp3852emp-3-3-etched.step / lp3852emp-3-3-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lp3852emp-3-3.step / lp3852emp-3-3.glb are the bare package body.
