YFW · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-252
79M15 from YFW, in a TO-252. 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 of the -15V regulator; the input is rated to -35V (absolute maximum) relative to it. |
| 2 | IN | power_in | Negative unregulated input voltage, absolute maximum -35V, recommended -18V to -30V for -15V output; also connected to the tab. |
| 3 | OUT | power_out | Regulated -15V output (-14.40V to -15.60V at 25°C), output current in excess of 1A with internal current limiting. |
