Slkor(SLKORMICRO Elec.) · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89
SL9350L28SQ 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 regulator, to which the input and output capacitors must return. |
| 2 | VIN | power_in | Power input pin with a recommended supply range of 2.5~6.5 V, and VIN must always be the dropout voltage higher than VOUT for the device to regulate properly. |
| 3 | VOUT | power_out | Regulated output pin that requires a minimum of 1uF capacitor from VOUT to ground for stability. |
