LP38511-1.8 800 mA Fast-Transient Response Low-Dropout Linear Voltage Regulator with Error Flag May 14, 2008 LP38511-1.8 800 mA Fast-Transient Response Low-Dropout Linear Voltage Regulator with Error Flag General 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 10uF ceramic capacitors, and has a fixed 1.8V output.
