The SGC21300 is a very high PSRR, very low noise band gap voltage reference that provides a fixed voltage outputs from inputs between 1.8V and 5.5V. The architecture of the SGC21300 enables the reference to be operated at a very low quiescent current while still realizing excellent DC and PSRR characteristics. The core includes a bias current generator with multiple outputs and a reference lock detector. Trimming is available for increased initial accuracy and temperature compensation. It is specified from TJ = - 40ºC to + 125ºC and is designed to achieve ±0.5 % overall accuracy after trim (over Load/Line/Temp).
