Regulator IC LP2989AIM-3.0

Precision Output: Guaranteed output voltage accuracy is 0.75% ("A" grade) and 1.25% (standard grade) at room temperature.

Error Flag: The built-in error flag goes low when the output drops approximately 5% below nominal.

Sleep Mode: The LP2989 draws less than 0.8 ?A quiescent current when shutdown pin is pulled low.

Ground Pin Current: Typically 3 mA @ 500 mA load, and 110 ?A @ 100 ?A load.

Dropout Voltage: Typically 310 mV @ 500 mA load, and 1 mV @ 100 ?A load.

Using an optimized VIP (Vertically Integrated PNP) process, the LP2989 delivers superior performance:

Output noise can be reduced to 18?V (typical) by connecting an external 10 nF capacitor to the bypass pin.

The LP2989 is a fixed-output 500 mA precision LDO regulator designed for use with ceramic output capacitors.
