8.2.2.2 Output Current

Depending on the input-output voltage differential, the output current must be limited to ensure maximum power

dissipation is not exceeded. The graph in Figure 1 shows the appropriate current limit for a variety of conditions.

8.2.2.3 Input Capacitor

If no power supply filter capacitor is used or if the device is placed more than four inches away from the capacitor

of the power supply, an additional capacitor placed at the input pin of the device helps bypass noise.

8.2.2.4 Output Capacitor

These devices are designed to be stable with no output capacitance and can be omitted from the design if

needed. However if large changes in load are expected, an output capacitor is recommended to improve the

transient response.

9 Power Supply Recommendations

The LM341 and LM78M05 devices are designed to operate from an input voltage supply range between

capacitor 0.1-µF or greater of any type is recommended.
