3 Description
The TPS7A53B is a low-noise (4.6μVRMS), ultra-low dropout linear regulator (LDO) capable of sourcing 3A with only 110m V of maximum dropout. The device output voltage is adjustable from 0.5V to 5.15V using an external resistor divider.
The bination of low noise (4.6μVRMS), high PSRR, and high output current capability makes the...
