Features
•Ultra low dropout voltage
•Guaranteed 500 mA continuous output current
•Very low output noise with external capacitor
•SO-8, Mini SO-8, 8 Lead LLP surface mount packages
•<0.8 µA quiescent current when shutdown
•Low ground pin current at all loads
•0.75% output voltage accuracy ("A" grade)
•High peak current capability (800 mA typical)
•Wide supply voltage range (16V max)
•Overtemperature/overcurrent protection
•-40°C to +125°C junction temperature range

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 µA load.

Sleep Mode: The LP2989 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 LP2989LV datasheet.

Applications
•Notebook/Desktop PC
•PDA/Palmtop Computer

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
