SGM2049XTRL20G/TR

SGM2049XTRL20G/TR is a high accuracy, low noise, very low dropout linear regulator. It is capable of supplying 2A output current with typical dropout voltage of only 75mV. The operating input voltage range is from 1.1V to 7V with BIAS and 1.4V to 7V without BIAS. The output voltage of the SGM2049 can be set from 0.8V to 3.95V in pin-selectable operation and adjusted from 0.8V to 5.2V by using an external resistor divider. Other features include logic-controlled shutdown mode, short-circuit current limit and thermal shutdown protection. It has automatic discharge function to quickly discharge VOUT in the disabled status. It is suitable for application which needs high accuracy, low noise and high current power supply, such as analogue-to-digital converters, digital-to-analogue converters and RF components. Application includes wireless equipment, industrial, instrumentation and medical, ADC and DAC, ATE.
