General Description

The LP2989LV is a 500 mA fixed-output voltage regulator designed to provide high performance and low noise in applications requiring output voltages < 2V.

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 LP2989LV delivers superior performance:

Ground Pin Current: Typically 3 mA @ 500 mA load, and 110 µA @ 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: Guaranteed output voltage accuracy is 0.75% ("A" grade) and 1.25% (standard grade) at room temperature.

For output voltages >= 2V, see LP2989 datasheet.

Features
