SY7208LABC from Silergy Corp, in a SOT-23-6. 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 | LX | power_out | Inductor switch node. Drain of the internal 150mΩ low-side NMOS. Connect the boost inductor between IN pin and LX pin; the external Schottky rectifier connects from LX to VOUT. Rated to 26V absolute max. |
| 2 | GND | power_in | Ground pin. Return for both signal and power currents. Maximize copper area to this pin for thermal and noise performance. |
| 3 | FB | input | Feedback pin. Connect resistor R1 between VOUT and FB and R2 between FB and GND to program output voltage: VOUT = 0.6V × (R1/R2 + 1). Internal reference is 0.6V (0.588V-0.612V). Recommended R1/R2 values 10k-1M. |
| 4 | EN | input | Enable control input. Drive high (>2V) to turn on the regulator; pull low (<0.4V) to shut down (ISHDN ≈ 15µA). Do not leave floating. Rated to 26V absolute max, so it may be tied directly to VIN. |
| 5 | IN | power_in | Bias/input supply pin. Operating range 3V to 25V (UVLO rising ~2.7V). Decouple to GND with a 1µF (10µF X5R recommended) low-ESR ceramic capacitor placed close to the IN and GND pins. |
| 6 | NC | unconnected | No internal connection. Leave floating or tie to a non-critical net at the designer's discretion. |
