DESCRIPTION

The LTM?4709 is a low voltage, triple 3A μModule

linear regulator offering a high power supply rejection

ratio (PSRR), ultralow noise, and ultrafast transient

response. The μModule regulator includes low dropout

linear regulators (LDO), capacitors, and resistors. Operating

over an input voltage range of 0.6V to 5.5V, the LTM4709

supports an output voltage range of 0.5V to 4.2V for

triple 3A channels with a typical dropout voltage of 45mV.

The output voltage is digitally configurable in 50mV

increments from 0.5V to 1.2V; 100mV increments from

1.2V to 1.8V; and discrete levels at 2V, 2.5V, 3V, 3.3V,

and 4.2V. A precision current monitor provides accurate

current monitoring for the energy management system

and current limit. The LTM4709 is ideal for RF communication,

noise-sensitive instrumentation, post-regulation

for switching regulators, high-performance FPGAs, and

microprocessors. Only input, output, and bias ceramic

capacitors are needed for its application.

Fault protection features include UVLO, power good, overcurrent,

and overtemperature protection. The LTM4709 is

offered in 6mm × 12mm × 1.92mm, 98-pin BGA package with 0.8mm ball pitch.
