Lewa Micro · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · DFN1x1-4L
LW5222N11E 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 that needs a low-ESR ceramic capacitor, nominally 1µF or larger from OUT to GND, and an internal pulldown discharges OUT when VEN is below VEN(LOW). |
| 2 | GND | power_in | Ground pin, which is also electrically connected to the thermal pad and should be tied to the GND plane. |
| 3 | EN | input | Enable pin: drive above VENH (1.5 V min) to turn the regulator on and below VENL (0.5 V max) to put it in shutdown, with the EN pin voltage rated 0 to 6.0 V. |
| 4 | VIN | power_in | Input pin with a recommended supply range of 1.5 V to 6.0 V, which should be decoupled with the recommended ceramic capacitor placed as close to the device as possible. |
| 5 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
