LDO Linear RegulatorsHow to use
Ceramic capacitors are recommended for the latest LDO regulators.
Select a capacitor whose ESR characteristic is within the hatched area in the figure titled ESR vs. Output Current on datasheets, even when you select a capacitor except a ceramic type.
R1116 Series Example
The relations between IOUT (Output Current) and ESR of an output capacitor are shown right.
The conditions when the white noise level is under 40 µV (Avg.) are shown by the hatched area in the graph.
|Noise Frequency Band||10 Hz to 1 MHz|
|Hatched Area||Noise level below 40 µV
