LPW5209AB5F

LOWPOWER · AC-DC Controllers and Regulators · SOT-23-5

LPW5209AB5F from LOWPOWER, in a SOT-23-5. Pinout and pin descriptions extracted from the datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VOUT power_out Switched output to the load; source of the internal N-channel high-side MOSFET. Voltage tracks VIN minus IOUT*RDS(ON) (typ. 80mΩ). Bypass with an output capacitor to meet USB inrush requirements.
2 GND power_in Device ground reference for internal circuitry and control signals.
3 ISET input Programmable current-limit set pin. Connect a resistor from ISET to GND to set the output current limit (e.g. RISET=10K→~680mA, 6.8K→~1000mA, 3.4K→~2000mA). Present on the adjustable LPW5209AB5F variant.
4 EN input Active-high device enable. VEN(H) ≥ 1.4V turns the switch on; VEN(L) ≤ 0.4V disables it (shutdown current ~0.1µA). Do not float; may be tied to VIN to keep the part permanently enabled. Must not go negative with respect to GND.
5 VIN power_in Input supply pin (2.5V to 6V, abs max 7V) and drain of the internal N-channel MOSFET. Bypass locally with a ceramic input capacitor.

CAD (KiCad official)

  • Symbol: LPW5209AB5F
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: lpw5209ab5f-etched.step / lpw5209ab5f-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lpw5209ab5f.step / lpw5209ab5f.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
lpw5209ab5f.step 85 KB You want the bare part, or you mark your own boards.
lpw5209ab5f-etched.step 2.1 MB You want the part with LPW5209AB5F already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 520 faces against 102 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:
