LP2989 Micropower/Low Noise, 500 mA Ultra Low-Dropout Regulator
For Use with Ceramic Output Capacitors
February 2005
LP2989
Micropower/Low Noise, 500 mA Ultra Low-Dropout
Regulator
For Use with Ceramic Output Capacitors
General Description
The LP2989 is a fixed-output 500 mA precision LDO regu-
lator 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) pro-
cess, 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.
