# SL9193M12SA

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

SL9193M12SA 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; the input and output capacitor ground connections must return to this pin using as wide and as short a copper trace as is practical. |
| 2 | VOUT | power_out | Regulated output voltage; the output must be bypassed with at least 1µF ceramic (X7R or X5R) placed as close as possible to VOUT and GND, and the output is limited to -0.3 V to VIN+0.3 V. |
| 3 | VIN | power_in | Power input with an operating supply range of 2 V to 6.5 V and an absolute maximum rating of -0.3 V to 7 V, decoupled with a 1µF ceramic capacitor placed as close as possible to the device. |
