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.

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
