Equivalent Series Resistance 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 40 μV (Avg.) are marked as the hatched area in the graph.

Measurement Conditions

Frequency Band: 10 Hz to 2 MHz

Temperature: −40°C to 85°C

Hatched Area: Noise level is under 40 V (Avg.)

C1, C2: 1.0 F or more
