ETA5055V250DS2F from ETA(钰泰), in a SOT-23-5. 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 | IN | power_in | Input supply pin; the input voltage range is 1.8V to 5.5V, and the minimum VIN is 1.8V or VOUT + VDROPOUT, whichever is greater. |
| 2 | GND | power_in | Ground pin. |
| 3 | EN | input | Enable pin: drive high to enable the IC and low to disable it, with logic low specified at 0.4V and logic high at 0.9V for 1.8V ≤ VIN ≤ 5.5V. |
| 4 | NC | unconnected | Listed as NA for the SOT23-5 package in the pin table (it is NC on DFN2x2-6 pins 2 and 5), so no function is assigned on this package. |
| 5 | OUT | power_out | Regulator output pin; continuous output current is 500 mA, with output current limit of 540 mA to 800 mA and foldback limit of 400 mA under hard short. |
