LT6658AIMSE-2.5#PBF

V-Ref Precision 2.5V 150mA Automotive 16Pin MSOP EP Tube

The is a precision dual output, high current, low noise voltage reference in 16 pin MSOP package. This 2.5V dual output reference combines performance of a low drift low noise reference and a linear regulator. Both outputs are ideal for driving precision reference inputs of high resolution ADCs and DACs even with heavy loading while simultaneously acting as output supplies powering microcontrollers and other supporting devices. Both outputs have same precision specifications and track each other over temperature and load. Both outputs are nominally 2.5V however each can be configured with external resistors to give an output voltage up to 6V. Using kelvin connections, the LT6658 typically has 0.1ppm/mA load regulation with up to 150mA load current. The outputs have excellent supply rejection and are stable with 1µF to 50µF capacitors. Typical applications include microcontroller with ADC/DAC applications, data acquisition systems and precision low noise regulators.
