LW5225N11E 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 should be connected to a low-ESR capacitor, with the nominal recommended value or larger from OUT to GND for best transient response, and an internal pulldown discharges OUT in shutdown (VEN < VEN(LOW)). |
| 2 | GND | power_in | Ground pin, which is the reference for the input and output capacitors and should be connected to a separate ground plane per the layout recommendation. |
| 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 the LDO into shutdown, with an EN pin voltage rating of 0 to 6.0 V. |
| 4 | VIN | power_in | Input pin with a supply range of 1.5 V to 6.0 V; use the recommended or larger ceramic capacitor from IN to ground, placed as close to the device as possible. |
| 5 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
