This micropower reference uses curvature compensation to obtain a low temperature coefficient and trimmed precision thin-film resistors to achieve high output accuracy. In addition, Output accuracy is further assured by excellent line and load regulation. Special care has been taken to minimize thermally induced hysteresis. However, since the LT1790-2.5 can also sink current, it can operate as a micropower negative voltage reference with the same performance as a positive reference. , LTC and LT are registered trademarks of Linear Technology Corporation.
