QUIETPOWER Output Ripple Attenuation SiP

section explains how to optimize the configuration of the QPO-1 for the voltage source used. The headroom voltage is the difference between the input and the output of the QPO-1 and is set by the selection of resistor RHR. Calculate RHR as shown. RHR = (QPOOUT / VHR ) x 2.5k (see Table 1 for example values) (2) RSS resistor sets the correction current requ.
