DESCRIPTION
The LP38513-ADJ Fast-Transient Response LowDropout
Voltage Regulator offers the highestperformance in meeting AC and DC accuracy requirements for powering Digital Cores. The LP38513-ADJ uses a proprietary control loop that enables extremely fast response to change in line conditions and load demands. Output
Voltage DC accuracy at 2.5% over line, load and full temperature range from -40°C to +125°C. The LP38513-ADJ is designed for inputs from the 2.5V, 3.3V, and 5.0V rail, is stable with 10 μF ceramic
capacitors, and has an adjustable output
voltage. The LP38513-ADJ provides excellent transient performance to meet the demand of high performance digital core ASICs, DSPs, and FPGAs found in highly-int...
