The LP2989LV 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 LP2989LV delivers superior performance:

Ground Pin Current: Typically 3 mA at 500-mA load, and 110 µA at 100-µA load.

Sleep Mode: The LP2989LV draws less than 0.8-µA 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: Output voltage accuracy is 0.75% (A grade) and 1.25% (standard grade) at room temperature.

For output voltages greater than or equal to 2 V, see the LP2989 (SNVS083) data sheet.
