L7905CD2T-TR from STMicroelectronics, in a TO-263-2. 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 |
|---|---|---|---|
| Tab | IN | power_in | DC input pin, electrically tied to the package's exposed metal tab (used for heatsinking); absolute maximum input voltage is -35 V for this -5 V output version (VO = -5 to -18 V range), with input typically -8 to -20 V during regulation per the L7905C electrical characteristics table. |
| 1 | OUT | power_out | Regulated negative output pin, nominal -5 V (min -4.8 V, max -5.2 V at TJ = 25°C), delivering up to 1.5 A output current with internal thermal-overload, short-circuit (2.1 A typ.), and output-transition SOA protection. |
| 2 | GND | power_in | Ground/common reference pin providing the return path for input and output currents (quiescent current typ. 3 mA flows through this pin). |
