The LP38512-ADJ Fast-Transient Response Low-Dropout Voltage Regulator offers the highest-performance in meeting AC and DC accuracy requirements for powering Digital Cores. The LP38512-ADJ uses a proprietary control loop that enables extremely fast response to change in line conditions and load demands. Output Voltage DC accuracy is specified at 2.5% over line, load and full temperature range from -40°C to +125°C. The LP38512-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 LP38512-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
  • 1.5A 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
