TPS7A53 Overview
The TPS7A53 is a low-noise (4.4 µVRMS), ultra-low dropout linear-regulator (LDO) capable of sourcing 3 A with only 110 mV of maximum dropout. The device output voltage is adjustable from 0.8 V to 5.2 V using an external resistor divider. The bination of low noise (4.4 µVRMS), high PSRR, and high output current capability makes the TPS7A53 an excellent choice to power noisesensitive ponents such as those found in...
