... RN5RT TYPICAL APPLICATION In the RN5RT Series, a constant voltage can be obtained without using Capacitor C1 and C2. However, when the wire connected long, use Capacitor C1. Transient noise of output voltage occurred due to load deviation can IN be reduced by using Capacitor C2. Insert Capacitors C1 and C2 with the capacitance of 0.1µF to 2.0µF between Input/Output Pins and GND Pin with minimum wiring ...
