TPS7A3501 - 1-A Power Filter

📥 Download Datasheet

General Description

The TPS7A3501 is a positive voltage, low-noise (3.8-µVRMS) power filter capable of sourcing a 1-A load suitable for quiet supply solutions.

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.
