The SGM2049 is a low noise, very low dropout linear regulator which operates from input voltage as low as 1.1V. It is capable of supplying 2A output current with typical dropout voltage of only 70mV. The SGM2049 output voltage is pin-selectable from 0.8V to 3.95V and adjustable from 0.8V to 5.2V using an external resistor divider.

The low noise, high PSRR and high output current capabilities make the SGM2049 ideal to power noise- sensitive devices such as analog-to-digital converters (ADCs), digital-to-analog converters (DACs) and RF components.

With very high accuracy, remote sensing, and soft-start capabilities to reduce inrush current, the SGM2049 ensures the optimal system performance for powering digital loads such as FPGAs, DSPs, and ASICs. These applications require low-input voltage, low-output voltage operation, the exceptional accuracy, remote sensing, excellent transient performance and soft-start capabilities.
