LP2989 Overview
The LP2989 is a fixed-output 500-mA precision LDO regulator designed for use with ceramic output capacitors. Output noise can be reduced to 18 μV (typical) by connecting an external 10-nF capacitor to the bypass pin. Using an optimized Vertically Integrated PNP (VIP) process, the LP2989 delivers superior performance:.
