LP38512-1.8  
1.5A Fast-Transient Response Low-Dropout Linear  
Voltage Regulator with Error Flag  
General Description  
Features  
The LP38512-1.8 Fast-Transient Response Low-Dropout  
Voltage Regulator offers the highest-performance in meeting  
AC and DC accuracy requirements for powering Digital  
Cores. The LP38512-1.8 uses a proprietary control loop that  
enables extremely fast response to change in line conditions  
and load demands. Output Voltage DC accuracy is guaran-  
teed at 2.5% over line, load and full temperature range from  
-40°C to +125°C. The LP38512-1.8 is designed for inputs  
from the 2.5V, 3.3V, and 5.0V rail, is stable with 10 μF 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 nom-  
inal value. The LP38512-1.8 provides excellent transient per-  
formance to meet the demand of high performance digital  
core ASICs, DSPs, and FPGAs found in highly-intensive ap-  
plications such as servers, routers/switches, and base sta-  
tions.
