Description
General part information
LP2989 Series
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:
