Description

The LD49150 is a high-bandwidth, low-dropout,

1.5A voltage regulator, ideal for powering core

voltages of low-power microprocessors. The

LD49150 implements a dual supply configuration

allowing for very low output impedance and very

fast transient response. The LD49150 requires a

bias input supply and a main input supply,

allowing for ultra-low input voltages on the main

supply rail. The input supply operates from 1.4V to

5.5V and the bias supply requires between 3V

and 6V for proper operation. The LD49150 offers

fixed output voltages from 0.8V to 1.8V and

adjustable output voltages down to 0.8V.

The LD49150 requires a minimum output

capacitance for stability, and work optimally with

small ceramic capacitors.

Applications

■ Graphics processors

■ PC Add-In Cards

■ Microprocessor core voltage supply

■ Low voltage digital ICs

■ High Efficiency Linear power supplies

■ SMPS post regulators
