ESR vs. Output Current
When using these ICs, consider the following points:
The relations between IOUT (Output Current) and ESR of an output capacitor are shown below.
The conditions when the white noise level is under 40µVrms (Avg.) are marked as the hatched area in the
graph.
Measurement conditions
• Frequency Band : 10Hz to 1MHz
• Temperature : −40°C to 85°C
• Hatched Area : Noise level is under 40µVrms (Avg.)
• CIN
: 4.7µF (KTD500B475M43A0T00)
• COUT
: 4.7µF (KTD500B475M43A0T00)
: 10.0µF (FK22Y5V1H106Z)
