LW5118N11E 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 of the LDO, factory-trimmed from 0.8V to 5.0V in 100mV steps (LW5118N11E is the 1.8V version), with at least 1µF ceramic output capacitor recommended for stability and placed no more than 0.5 inch from this pin. |
| 2 | GND | power_in | Ground reference pin; for best PSRR and transient response, the VIN and VOUT ground planes should connect only at this GND pin. |
| 3 | EN | input | Chip enable input with recommended range 0 to 6.0V (absolute maximum -0.3 to 7.0V); VENH is 1.5V minimum and VENL is 0.5V maximum. |
| 4 | VIN | power_in | Power supply input with recommended operating range 1.5V to 6.0V (absolute maximum -0.3 to 7.0V), with at least 1µF input capacitor placed within 0.5 inch of this pin. |
| 5 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
