Power Supply Noise Reduction - Designer’s Guide
designers-guide.orgMar 10, 2019 · Due to the finite bandwidth of all voltage regulators, their output impedance increases with frequency. This can be modeled as an inductor in series with the output. Typical values lie between 1 μH and 2 μH for a linear three terminal regulator. The output impedance of switching regulators varies wide ly and should be measured for each case.
