LW5218N11E

Lewa Micro · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · DFN1x1-4L

LW5218N11E from Lewa Micro, in a DFN1x1-4L. 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 VOUT power_out Regulated output pin, fixed at 1.8 V for LW5218N11E per the order table; use at least a 1 µF low-ESR ceramic capacitor from OUT to GND, and an internal pulldown discharges OUT when the regulator is in shutdown (VEN < VEN(LOW)).
2 GND power_in Ground pin; the separate VIN and VOUT ground planes should connect only at this GND pin for best PSRR, noise and transient response.
3 EN input Enable pin: drive above VEN(HI) (1.5 V min) to turn the regulator on and below VEN(LO) (0.5 V max) to put it into shutdown, with the EN pin voltage rated 0 to 6.0 V.
4 VIN power_in Input supply pin, operating range 1.5 V to 6.0 V (absolute maximum -0.3 V to 7.0 V), to be decoupled with a ceramic capacitor placed as close to the pin as possible.
5 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
