Slkor SLKORMICRO Elec · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5
SL75BL50SE 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 | GND | power_in | Ground reference pin; the input and output capacitor grounds must return to this pin through as wide and short a copper trace as practical. |
| 2 | VIN | power_in | Power input, rated up to 36 V (absolute maximum supply -0.3 V to +40 V), with a 1 µF ceramic input capacitor recommended as close to the pin as possible. |
| 3 | VOUT | power_out | Regulated fixed output (2.8 V to 5.0 V depending on the variant), rated for up to 150 mA, requiring a minimum 10 µF X7R or X5R ceramic output capacitor placed close to VOUT and GND. |
| 4 | NC | unconnected | Not connected; listed as NC in the pin description table, so it is not used by the regulator. |
| 5 | NC | unconnected | Not connected; listed as NC in the pin description table, so it is not used by the regulator. |

Materials and finish
As the datasheet states them (page.json metadata.appearance; the 3D model's colours follow it).
| Part | Material | Colour / plating | Datasheet says | Page |
|---|---|---|---|---|
| contacts | copper | must be back to the SL75B Series ground pin using as wide and as short of a copper trace as is | 5 |
