This reference design demonstrates a low-noise: low-dropout (LDO): high-current power stage with no voltage-bias-rail requirement utilizing the LP5922 LDO linear regulator. The power stage demonstrated is ideal for industrial applications. Within industrial applications: low-noise power is often achieved by introducing an LDO at the point-of-load to clean up voltage ripple from a previous switching regulator power stage. LP5922 device makes this possible in an efficient manner by supporting very low dropout: which also eliminates any need for a voltage bias at its input.
