Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-92
LM78L12ACZ from Texas Instruments, in a TO-92. 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 | VOUT | output | Output voltage pin providing 12V nominal regulated output; output capacitor (0.1µF recommended) should be placed close to VOUT and GND pins. |
| 2 | GND | power_in | Ground reference pin. |
| 3 | VIN | power_in | Input supply voltage pin; maximum 30V recommended (35V absolute maximum for old die); input capacitor (0.33µF recommended) should be placed close to VIN and GND pins. |
