Slkor SLKORMICRO Elec · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89
SL79L12 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 | Common ground reference pin of the regulator; bypass capacitors should be located as close as possible to the regulator for optimum stability and transient response. |
| 2 | IN | power_in | Negative unregulated input; absolute maximum input voltage is -35 V, and the output is specified for inputs between -14.5 V and -27 V. |
| 3 | OUT | power_out | Regulated negative output, nominally -12 V (Vo -11.4 V to -12.6 V over the stated conditions), with maximum output current IOM of 0.1 A. |
