LP2989 Micropower/Low Noise, 500 mA Ultra Low-Dropout Regulator For Use with Ceramic Output Capacitors March 2000 LP2989 Micropower/Low Noise, 500 mA Ultra Low-Dropout Regulator For Use with Ceramic Output Capacitors General Description The LP2989 is a fixed-output 500 mA precision LDO regulator designed for use with ceramic output capacitors. Output noise can be reduced to 18µV (typical) by connecting an external 10 nF capacitor to the bypass pin. Using an optimized VIP™ (Vertically Integrated PNP) process, the LP2989 delivers superior performance: Dropout Voltage: Typically 310 mV @ 500 mA load, and 1 mV @ 100 µA load. Ground Pin Current: Typically 3 mA @ 500 mA load, and 110 µA @ 100...
