For Stable Operation
Phase Compensation
In these ICs, phase compensation is externally made for securing stable operation even if the load current is
varied. For this purpose, be sure to use a capacitor for the output pin with good frequency characteristics and
ESR (Equivalent Series Resistance) of which is in the range described as follows:

Measuring Circuit for white noise; R1152NxxxB
The relations between IOUT (Output Current) and ESR of Output Capacitor are shown below. The conditions
when the white noise level is under 40
μV (Avg.) are marked as the hatched area in the graph.
