The device output voltage is pin-programmable from 0.8 V to 3.95 V and adjustable from 0.8 V to 5.15 V using an external resistor divider. The combination of low-noise, high-PSRR, and high output-current capability makes the TPS7A84A ideal to power noise-sensitive components such as those found in high-speed communications, video, medical, or test and measurement applications. The high performance ...
