Power filters, such as the TPS7A3501, provide voltage regulation across the input and output terminals with high efficiency (low insertion loss), and power-supply rejection. The device is ideally suited as a noise filter for 3.3-V, 2.5-V, and 1.8-V supplies at up to 1 A. The input-to-output voltage regulation is also userprogrammable, from 200 mV to 500 mV, with a sing...
