SL9350L18SQ from Slkor SLKORMICRO Elec, in a SOT-89. 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 SL9350 regulator; the datasheet gives no further electrical limit for this pin. |
| 2 | VIN | power_in | Power input with a 2.5V to 6.5V supply range; VIN must always be higher than VOUT by the dropout voltage for the device to regulate properly, and a 1uF input capacitor is recommended to keep VIN from sagging below dropout during load transients. |
| 3 | VOUT | power_out | Regulated output (1.2V to 3.6V in 0.1V steps for this variant, 1.8V in the MPN); a minimum 1uF capacitor must be connected from VOUT to ground for stability. |
