DESCRIPTION
The LP38512-ADJ Fast-Transient Response Low-
Dropout Voltage Regulator offers the highestin
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.
