LP38512-ADJ

1.5A Fast-Transient Response Adjustable Low-Dropout

Linear Voltage Regulator

General Description

Features

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 guaran-

teed 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
