The Analog Devices LT1021DCS8-5#TRPBF is a fixed 5 V series voltage reference using a buried Zener architecture, supplied in an 8-pin SOIC N package. It sources up to 10 mA of output current with a 20 ppm/C temperature coefficient, drawing 1.5 mA operating supply current and 1.2 mA quiescent current. The LT1021DCS8-5#TRPBF is a commercial-temperature part specified from 0 C to 70 C, is RoHS compliant and lead free, and ships on tape and reel. Buried Zener references place the Zener junction below the die surface, away from surface contamination and stress, which is the classic approach to low noise and long-term output stability.

A precision 5 V series reference sets the full-scale accuracy of everything downstream of it, so parts like this are used to bias ADC and DAC reference inputs, define thresholds in precision comparators, anchor calibration and test equipment, and supply stable excitation to bridge and strain-gauge sensors. Low-noise buried Zener designs are chosen over bandgap references where long-term drift and output noise matter more than low supply voltage or minimum power draw. The 10 mA output rating means it can drive several reference loads and a modest bias network without an added buffer. Typical buyers are precision analog and instrumentation designers, test and measurement OEMs, and industrial process-control manufacturers.
