Looking over the LM723 datasheet shows that it has better ripple rejection than standard 3 leg regulators.
This is done with a 5uf bypass cap across the non inverting input and ground as seen in fig 1. The caption says its good for 2-7 volts. To go above 7v the setup is different as seen in fig 2. Can the cap be used in the same place and also achieve the same performance?
