# SL9650M33SA

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

SL9650M33SA from Slkor SLKORMICRO Elec, in a SOT-23. 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 (datasheet lists GND as Ground with no further limit stated). |
| 2 | VOUT | power_out | Regulated output; a minimum 1µF capacitor from VOUT to ground is required for stability. |
| 3 | VIN | power_in | Input supply pin, rated 1.7V to 7V (recommended operating range; absolute maximum input 8.5V), and must stay above VOUT by the dropout voltage for proper regulation. |
