The LTM4709 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.
