Slkor SLKORMICRO Elec · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-3
SL75BL50SC from Slkor SLKORMICRO Elec, in a SOT-23-3. 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 | GND | power_in | Ground reference pin; the datasheet requires the ground returns of the input and output capacitors to use as wide and as short a copper trace as is practical to a single ground point. |
| 2 | VOUT | power_out | Regulated fixed output (2.8V to 5V variants, 150mA maximum output current), which requires a minimum 10µF X7R or X5R ceramic output capacitor placed as close as possible to VOUT and GND. |
| 3 | VIN | power_in | Power input rated up to 36V (absolute maximum supply voltage 40V), which should be decoupled to GND with a 1µF ceramic capacitor placed as close as possible to the device. |
