Analog Devices LTM4709
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. The LTM4709 is ideal for RF communication, noise-sensitive instrumentation, post-regulation for switching regulators, high-performance FPGAs, and microprocessors.
