General Description

The RTQ2539A is a high-current (3A), low-noise (6.8μVRMS), high accuracy (1% over line, load, and temperature), low-dropout linear regulator (LDO) capable of sourcing 3A with extremely low dropout (max.

130mV).

The device supports single input supply voltage as low to 1.1V, which makes it easy to use.
