DESCRIPTION  
The LP8900 is a dual linear regulator capable of  
supplying 200 mA output current per regulator.  
Designed to meet the requirements of RF/Analog  
circuits, the LP8900 provides low device noise, High  
PSRR, low quiescent current and superior line  
transient response figures.  
110 mV Dropout at 200 mA Load  
48 µA Quiescent Current per Regulator  
80 µs Startup Time  
Using new innovative design techniques the LP8900  
offers class-leading device noise performance without  
a noise bypass capacitor.  
Stable with Ceramic Capacitors as Small as  
0402  
•
Thermal-Overload and Short-Circuit Protection  
The LP8900 is designed to be stable with space  
saving ceramic capacitors as small as 0402 case  
size, enabling a solution size <4mm 2.
