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.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
