Texas Instruments' 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.

The input-to-output voltage regulation is also user-programmable from 200 mV to 500 mV with a single external resistor. If no resistor is used, the TPS7A3501 provides 330 mV of input-to-output voltage regulation. The device is stable with 10 µF input and output ceramic capacitors and a 10 nF noise-reduction ceramic capacitor.

The TPS7A3501 is fully specified over a wide temperature of –40°C to +125°C. The device is offered in a low thermal resistance, 2 × 2 mm SON-6 package. Unlike passive filters, the TPS7A3501 provides thermal and current protection for itself and surrounding circuitry.
