SNVS083O –FEBRUARY 2005–REVISED MARCH 2015
LP2989 Micropower and Low-Noise, 500-mA Ultra Low-Dropout Regulator for Use With
Ceramic Output Capacitors Features 3 Description

The LP2989isa fixed-output 500-mA precision LDO 2.1-Vto 16-V Input Voltage Range regulator designed for use with ceramic output• 2.5-Vto 5-V Fixed Output Voltage Options capacitors.• Ultra-Low Dropout Voltage Output noise can be reducedto 18 μV (typical) by• 500-mA Continuous Output Current connectingan external 10-nF capacitorto the bypass Very Low Output Noise With External Capacitor pin. < 0.8-µA Quiescent Current When Shutdown Using an optimized Vertically Integrated PNP (VIP) Low Ground Pin CurrentatAll Loads process, the LP2989 delivers superior performance: Dropout Voltage: Typically 310 mVat 500-mA• 0.75% Output Voltage Accuracy(A Grade)
load, and1 mVat 100-µA load.• High Peak Current Capability (800-mA typical) • Ground Pin Current: Typically3 mAat 500-mA• Overtemperature and Overcurrent Protection load, and 110 µAat 100-µA load.• −40°Cto 125°C Junction Temperature Range • Sleep Mode: The LP2989 draws less than 0.8-µA
quiescent current when SHUTDOWN pinis pulled2 Applications low. Notebooks and Desktop PCs • Error Flag: The built-in error flag goes low when
the output drops approximately 5% below• PDAs and Palmtop Computers nominal.• Wireless Communication Pins • Precision Output: Output voltage accuracyis• SMPS Post-Regulators 0.75% (A grade) and 1.25% (standard grade)at
room temperature.
For output voltages<2V, see LP2989LV (SNVS086)
data sheet.
