SL7603P50M5R from Slkor SLKORMICRO Elec, 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 | VIN | power_in | Input supply pin, operating input voltage 3.5V to 15V (absolute maximum 18V), with a 1uF input capacitor recommended. |
| 2 | GND | power_in | Ground pin (Vss in the block diagram). |
| 3 | CE | input | Chip enable input pin; the datasheet text gives no threshold levels or polarity for it. |
| 4 | NC | unconnected | No connect pin with no internal function stated. |
| 5 | VOUT | power_out | Regulated 5.0V output (±2%) for the SL7603P50, up to 500mA, with a 1uF tantalum or 6.8uF ceramic output capacitor recommended. |
