LP38693MP-3.3

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

LP38693MP-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 EN input Enable input for the LP38693 (SOT-223 package); pulling the pin high or low turns the regulator output on or off. The pin must be below the VEN(OFF) threshold of 0.4 V (max, full temp range) to disable, and above VEN(ON) (1.8 V at VIN=4V, 3.0 V at VIN=6V, 4.0 V at VIN=10V, full temp range) to fully enable; enable-pin leakage is -1 µA to 1 µA (typ 0.001 µA) at VEN=0V or 10V.
2 NC unconnected No internal connection; this pin is not bonded to the die.
3 OUT power_out Regulated output voltage pin (3.3 V nominal for this -3.3 variant, ±2% accuracy at 25°C, ±4% over the full operating temperature range), rated for load currents from 100 µA to 0.5 A with a typical dropout of 65 mV at 100 mA and 330 mV at 500 mA (VO=3.3V).
4 IN power_in Input supply voltage to the regulator; recommended operating range is 2.7 V to 10 V, with an absolute maximum rating of -0.3 V to 12 V with respect to GND.
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-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: lp38693mp-3-3-etched.step / lp38693mp-3-3-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lp38693mp-3-3.step / lp38693mp-3-3.glb are the bare package body.
