LW5218A23E

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

LW5218A23E 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 pin; use the recommended value or a larger ceramic capacitor from IN to ground, placed as close to the device as possible, for best transient response and minimum input impedance.
2 GND power_in Ground pin.
3 EN input Enable pin: drive EN greater than VEN(HI) to turn the regulator on, and drive EN less than 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 pin; connect a low-ESR capacitor, using the nominal recommended value or larger from OUT to GND, and an internal pulldown discharges OUT when the regulator is in shutdown (VEN < VEN(LOW)).
