LW5228N11E

Lewa Micro · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · DFN-4L(1x1)

LW5228N11E from Lewa Micro, in a DFN-4L(1x1). 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 that needs a low-ESR capacitor of at least the recommended nominal value (1 µF minimum per the Output Capacitor Selection section) from OUT to GND, and an internal pulldown discharges OUT when the regulator is in shutdown.
2 GND power_in Ground pin, which should connect to the separate GND plane used for the device.
3 EN input Enable pin: drive EN above VEN(HI) to turn the regulator on and below VEN(LO) to put the LDO into shutdown mode.
4 VIN power_in Input pin that should have the recommended value or larger ceramic capacitor from IN to ground, placed as close to the device as possible for best transient response.
5 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
