LP38511-1.8 Datasheet | National Semiconductor

Description 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 10u F 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.
