Recommended output capacitor 0.1 μF to ground for stability and transient response. |+| 2 | GND | power_in | Common ground reference. On SOT-89 this pin is also electrically tied to the large metal heat-spreader tab on the underside of the package. |+| 3 | Input | power_in | Unregulated DC input, 7 V to 35 V (up to 40 V for the 24 V option, not applicable to 78L05).
