Slkor(SLKORMICRO Elec.) · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-3
SL75BL33SC 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 pin, the common return for the input and output capacitors and the device. |
| 2 | VOUT | power_out | Regulated output voltage, fixed between 2.8V and 5.0V, which needs a minimum 10µF ceramic output capacitor (X7R or X5R) placed close to the pin for stability. |
| 3 | VIN | power_in | Power input voltage, rated up to 36V per the features list, with a 1µF ceramic input capacitor recommended close to the pin. |
