RP102N331D-TR

LOW NOISE 300mA LDO REGULATOR

RICOH Co.,Ltd. 

ESR vs. Output Current

When using these ICs, consider the following points:

RP102x

NO.EA-141-160705

The relations between IOUT (Output Current) and ESR of an output capacitor are shown below.

The conditions when the white noise level is under 40V (Avg.) are marked as the hatched area in the graph.
