SY8201CABC 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 | BS | passive | Boot-strap pin. Supplies gate drive voltage for the internal high-side NMOS. Decouple to LX with a 100nF (0.1uF) low-ESR ceramic capacitor. |
| 2 | GND | power_in | Ground reference pin. Also serves as the case position for theta_JC thermal measurement; maximize copper area to this pin for best thermal and noise performance. |
| 3 | FB | input | Output feedback pin. Connect to the center of an external resistor divider from VOUT to program the output voltage: Vout = 0.6V * (1 + R1/R2). Internal reference is 0.6V +/-2%. |
| 4 | EN | input | Enable control input. Pull high (>1.5V) to enable the regulator; pull low (<0.4V) to shut down (I_SHDN < 5uA typ). Do not float. Absolute max VIN + 0.3V. |
| 5 | IN | power_in | Power input pin, 4.5V to 27V operating (30V absolute max). Decouple to GND with at least 1uF ceramic capacitor (4.7uF X5R low-ESR recommended) placed close to the pin. |
| 6 | LX | power_out | Switching node. Connect to the external inductor. Internal high-side (350mOhm) and low-side (150mOhm) MOSFETs switch this node between IN and GND. Minimize copper area for noise reduction. |
