The LP2989 is a fixed-output 500 mA precision LDO regulator designed for use with ceramic output capacitors. Output noise can be reduced to 18uV (typical) by connecting an external 10 nF capacitor to the bypass pin. Using an optimized VIP(TM) (Vertically Integrated PNP) process, the LP2989 delivers superior performance: Dropout Voltage: Typically 310 mV @ 500 mA load, and 1 mV @ 100 uA load. Ground Pin Current: Typically 3 mA @ 500 mA load, and 110 uA @ 100 uA load. Sleep Mode: The LP2989 draws less than 0.8 uA quiescent current when shutdown pin is pulled low. Error Flag: The built-in error flag goes low when the output drops approximately 5% below nominal. Precision Output: Guaranteed output voltage accuracy is 0.75% ("A" grade) and 1.25% (standard grade) at room temperature. For output voltages < 2V, see LP2989LV data sheet.
