Input Transient/Load Transient vs. Output Capacity (C2)
R1524 performs a stable operation by using 0.1 µF of ceramic capacitor as the output capacitor. However, the
variation of output voltage may not meet the demand of the system when input voltage and load current vary. In
such cases, the variation of output voltage can be minimized significantly by using 10 µF or higher ceramic
capacitor. When using a high-capacity electrolytic capacitor for the output line, place the electrolytic capacitor a
few centimeters apart from the IC after arranging the ceramic capacitor close to the IC.
