LP2989 Datasheet (Texas Instruments) - 500-mA Ultra Low-Dropout Regulator

LP2989, 500-mA Ultra Low-Dropout Regulator

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 sup
