Features • 2.25V to 5.5V Input Voltage Range • Adjustable Output Voltage Range of 0.5V to 3.3V • 800mA Output Load Current • ±2.0% Accuracy over Line, Load, and Full-Temperature Range from -40°C to +125°C • Stable with tiny 10 uF ceramic capacitors • Enable pin • Typically less than 1uA of Ground pin current with Enable pin low • 25dB of PSRR at 100 kHz • Over-Temperature and Over-Current Protection • PSOP-8 and TO-263 THIN Surface Mount Packages Description The LP38511-ADJ Fast-Transient Response Low-Dropout Voltage Regulator offers the highest-performance in meeting AC and DC accuracy requirements for powering Digital Cores. The LP38511-ADJ 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-ADJ is designed for inputs from the 2.5V, 3.3V, and 5.0V rail, is stable with 10 uF ceramic capacitors, and has an adjustable output voltage. The LP38511-ADJ 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. Applications • Digital Core ASICs, FPGAs, and DSPs • Servers • Routers and Switches • Base Stations • Storage Area Networks • DDR2 Memory

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
