Final Electrical Specifications LT1790-2.5 2.5V Micropower SOT-23 Low Dropout Reference March 2000 Features s DESCRIPTIO s s s s s s High Accuracy: A Grade- 0.05% Max B Grade- 0.1% Max Low Drift: A Grade- 10ppm/°C Max B Grade- 25ppm/°C Max Low Supply Current: 60µA Max Sinks and Sources: 5m A Min Low Dropout Voltage Guaranteed Operational - 40°C to 125°C Wide Supply Range: 2.6V to 18V The LT®1790-2.5 is a SOT-23 micropower low dropout series reference that bines high accuracy and low drift with low power dissipation and small package size. This micropower reference uses curvature pensation to obtain a low temperature coefficient and trimmed precision thin-film resistors to achieve high output accuracy. In addition, the LT1790-2.5 uses post-package trimming to greatly reduce the temperature coefficient and increase the output accuracy. Output accuracy is further assured by excellent line and load regulation. Special care has been taken to minimize thermally induced hysteresis. The LT1790-2.5 is ideally suited for battery-operated systems because of its small size, low supply current and reduced dropout voltage. This reference provides supply current and power dissipation advantages over shunt references that must idle the entire load current to operate. 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.
