DESCRIPTION
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.
