LP38693MP-5.0

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

LP38693MP-5.0 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 EN input Enable pin that allows the part to be turned ON and OFF by pulling this pin high or low (LP38693 only); no internal pull-up/pull-down, so it must be actively or passively terminated.
2 NC unconnected No internal connection.
3 OUT power_out Regulated output voltage of the LDO.
4 IN power_in Input supply voltage to the regulator (2.7 V to 10 V recommended operating range).
5 GND power_in Circuit ground for the regulator; for the SOT-223 package this pin is thermally connected to the die and functions as a heat sink when soldered to a large copper plane.

CAD (KiCad official)

  • Symbol: LP38693MP-5.0
  • 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: lp38693mp-5-0-etched.step / lp38693mp-5-0-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lp38693mp-5-0.step / lp38693mp-5-0.glb are the bare package body.
