ETA5053V280DF1E from etasolution, in a DFN1x1-4. 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 | Regulator output pin that delivers up to the 300 mA continuous output current, with absolute maximum voltage of -0.3 V to 6 V. |
| 2 | GND | power_in | Ground pin serving as the regulator's ground reference. |
| 3 | EN | input | Enable input: drive high to enable the regulator and low to disable it, with logic low at most 0.4 V and logic high at least 1.4 V for 1.8 V ≤ VIN ≤ 6 V, and it can be tied to VIN if unused. |
| 4 | VIN | power_in | Input supply pin with an input voltage range of 1.6 V to 6.0 V and an absolute maximum rating of -0.3 V to 6 V. |
| 5 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
