Typical Application
The TPS7A3501 is well-suited for use as a filter for switching power supplies. The high PSRR of the device
significantly reduces the ripple caused by the switching frequency as well as the subsequent harmonic
frequencies. Figure 23 shows a schematic for filtering the output of a switching regulator using the TPS7A3501 to
power an ADC.
