3 Description
The TPS7A53 is a low-noise (4.4 µVRMS), ultra-low dropout linear-regulator (LDO) capable of sourcing 3 A with only 110 m V 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...
