Overview
The LT1021DCS8-7#PBF, produced by Analog Devices Inc., is a precision voltage reference known for its ultralow drift and noise, excellent long-term stability, and high immunity to input voltage variations. This component is part of the LT1021 series, which offers reference outputs of 5V, 7V, and 10V. The LT1021DCS8-7#PBF specifically provides a 7V reference voltage and can be used as a shunt regulator with the same precision characteristics as the three-terminal connection. It is based on a buried zener diode structure, which enhances temperature drift and time stability compared to surface breakdown devices and even the best bandgap references.
