The LP38513-ADJ Fast-Transient Response Low-Dropout Voltage Regulator offers the highest-performance 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-intensive applications such as servers, routers/switches, and base stations.

  • 2.25V to 5.5V Input Voltage Range
  • Adjustable Output Voltage Range of 0.5V to 4.5V
  • 3.0A Output Load Current
  • ±2.0% Accuracy over Line, Load, and Full-Temperature Range from -40°C to +125°C
  • Stable with tiny 10 µF ceramic capacitors
  • Enable pin
  • Typically less than 1 µA of Ground pin current when Enable pin is low
  • 25dB of PSRR at 100 kHz
  • Over-Temperature and Over-Current Protection
  • TO-263 THIN 5-Pin Surface Mount Package
