R1183Z
ESR vs. Output Current
The relations between IOUT (Output Current) and ESR of an output capacitor are shown above. The conditions
when the white noise level is under 40µV (Avg.) are marked as the hatched area in the graph.
<Measurement conditions>
(1) VIN=VOUT+1V
(2) Frequency Band: 10Hz to 2MHz (BW=30Hz)
(3) Temperature: −40°C to 85°C
