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 m V to 500 m V, with a single external resistor. If no resistor is used, the TPS7A3501 provides 330 m V of input-to-output voltage regulation. The device is stable with 10-µF input and output ceramic capacitors and a 10-n F 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-mm × 2-mm, WSON-6 package. Unlike passive filters, the TPS7A3501 provides thermal and current protection for itself and surrounding circuitry.
