LW5433A23E

Lewa Micro · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5L

LW5433A23E from Lewa Micro, in a SOT-23-5L. 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 VIN power_in Input supply pin (1.9 V to 5.5 V); use the recommended or larger ceramic input capacitor placed as close to the device as possible.
2 GND power_in Ground pin.
3 EN input Enable pin: drive above VEN(HI) to turn the regulator on, and drive below VEN(LO) to put the LDO into shutdown mode.
4 NC unconnected No internal connection; the datasheet says to ground this pin for better thermal performance.
5 VOUT power_out Regulated output (1.2 V to 5.0 V) that needs a low-ESR capacitor, using the nominal recommended value or larger from OUT to GND; an internal pulldown discharges OUT in shutdown.

CAD (KiCad official)

  • Symbol: LW5433A23E
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5L (KiCad packages3D, STEP)
  • 3D model files: lw5433a23e-etched.step / lw5433a23e-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lw5433a23e.step / lw5433a23e.glb are the bare package body.
