SL4264-2 from Slkor(SLKORMICRO Elec.), in a SOT-223-3. 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 | I | power_in | Input voltage pin, decoupled with a ceramic capacitor connected directly to ground; the input operates over 5.5V to 42V with an absolute maximum of 42V. |
| 2 | GND | power_in | Chip ground pin, the reference for all voltages on the device. |
| 3 | Q | power_out | Regulated 5V output, which requires an output capacitor of at least 1uF with ESR of 4Ω or less connected to ground for loop stability. |
