# SL9350L33SC

**Slkor SLKORMICRO Elec** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-3

SL9350L33SC 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 for the regulator; the datasheet recommends a clean analog ground return for the input and output capacitors located within 1cm of the pins. |
| 2 | VOUT | power_out | Regulated 3.3V output; a minimum 1uF capacitor must be connected from VOUT to ground for stability, and the recommended maximum output current is 300mA (absolute maximum 400mA). |
| 3 | VIN | power_in | Power input with a recommended supply range of 2.5V to 6.5V (absolute maximum -0.3V to 8V), which must remain at least the dropout voltage above VOUT and be decoupled with about 1uF to 4.7uF to ground. |
