LD49150

1.5A Very low drop for low output voltage regulator

Feature summary

■ Input voltage range:

V_I= 1.4V to 5.5V

V_BIAS= 3V to 6V

■ Stable with ceramic capacitor

1.5% initial tolerance

■

■ Maximum dropout voltage (V_I- V_O) of 200mV

PPAK

over temperature

■ Adjustable output voltage down to 0.8V

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.

■ Ultra fast transient response (up to 10MHz

bandwidth)

■ Excellent line and load regulation

specifications

The LD49150 requires a minimum output

capacitance for stability, and work optimally with

small ceramic capacitors.

■ Logic controlled shutdown option

■ Thermal shutdown and current limit protection

■ Junction temperature range: –25°C to 125°C

Applications

Description

■ Graphics processors

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,

■ PC Add-In Cards

■ Microprocessor core voltage supply

■ Low voltage digital ICs

■ High Efficiency Linear power supplies

■ SMPS post regulators

allowing for ultra-low input voltages on the main

supply rail. The input supply operates from 1.4V to

Order codes
