ETA5050V33S2F from etasolution, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VIN | power_in | Input supply pin. Operating input voltage range 1.6V to 6.0V (absolute max -0.3V to 6V). Bypass with a 2.2µF ceramic capacitor to GND close to the pin. |
| 2 | GND | power_in | Ground pin. Common return for input, output, and enable references. |
| 3 | EN | input | Enable pin. Drive high (VIH >= 1.4V) to enable the regulator; drive low (VIL <= 0.4V) to disable and enter <1µA shutdown. Can be tied to VIN if not used. Internal 3MΩ resistor to GND; input current ~1µA at VEN=3V. |
| 4 | NC | unconnected | Not connected. Leave floating or tie to GND per board layout preference. |
| 5 | VOUT | power_out | Regulator output. Fixed 3.3V output (per V33 ordering code), ±2% accuracy, 500mA continuous current capability. Bypass with a 1µF ceramic capacitor to GND. Optional internal 1kΩ discharge resistor (present on 'D' suffix variants; the V33 suffix indicates no discharge). |
