LP38511,pdf datasheet (800 mA

The LP38511-1.8 Fast-Transient Response Low-Dropout
Voltage Regulator offers the highest-performance in meeting
AC and DC accuracy requirements for powering Digital
Cores. The LP38511-1.8 uses a proprietary control loop that
enables extremely fast response to change in line conditions
and load demands. Output Voltage DC accuracy is guaranteed
at ±2.5% over line, load and full temperature range from
-40°C to +125°C. The LP38511-1.8 is designed for inputs
from the 2.5V, 3.3V, and 5.0V rail, is stable with 10uF ceramic
capacitors, and has a fixed 1.8V output. An Error Flag feature
monitors the output voltage and notifies the system processor
when the output voltage falls more than 15% below the nominal
value. The LP38511-1.8 provides excellent transient performance
to meet the demand of high performance digital
core ASICs, DSPs, and FPGAs found in highly-intensive applications
such as servers, routers/switches, and base stations.
