Micropower/Low Noise, 500 mA Ultra Low-Dropout
Regulator
For Use with Ceramic Output Capacitors
General Description
The LP2989isa fixed-output 500 mA precision LDO regu-
lator designedfor use with ceramic output capacitors.
Output noise canbe reducedto 18µV (typical)by connecting external10nF capacitortothe bypass pin.
Usingan optimized VIP™ (Vertically Integrated PNP) pro-
cess, the LP2989 delivers superior performance:
Dropout Voltage: Typically 310 mV@ 500 mA load, and1@ 100µA load.
Ground Pin Current: Typically3 mA@ 500 mA load, and
110µA@ 100µA load.
Sleep Mode: The LP2989 draws less than0.8µA quiescent
current when shutdownpinis pulled low.
Error Flag: The built-in error flag goes low when the output
drops approximately 5% below nominal.
Precision Output: Guaranteed output voltage accuracyis
0.75% (“A” grade) and 1.25% (standard grade)at room
temperature.
For output voltages< 2V, see LP2989LV datasheet.
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 <0.8µA quiescent current when shutdown Low groundpin currentatall 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˚Cto +125˚C junction temperature range
