LT1790 Micropower SOT-23 Low Dropout Reference Family FEATURES DESCRIPTION n High Accuracy: The LT 1790 is a family of SOT-23 micropower low dropout A Grade0.05% Max series references that combine high accuracy and low drift B Grade0.1% Max with low power dissipation and small package size. These n Low Drift: micropower references use curvature compensation to A Grade10ppm/C Max obtain a low temperature coefficient and trimmed preci- B Grade25ppm/C Max sion thin-film resistors to achieve high output accuracy. In n Low Thermal Hysteresis 40ppm (Typical) 40C to 85C addition, each LT1790 is post-package trimmed to greatly n Low Supply Current: 60A Max reduce the temperature coefficient and increase the output n Sinks and Sources Current accuracy. Output accuracy is further assured by excellent n Low Dropout Voltage line and load regulation. Special care has been taken to n Guaranteed Operational 40C to 125C minimize thermally induced hysteresis. n Wide Supply Range to 18V The LT1790s are ideally suited for battery-operated n Available Output Voltage Options: 1.25V, 2.048V, systems because of their small size, low supply current 2.5V, 3V, 3.3V, 4.096V and 5V and reduced dropout voltage. These references provide n Low Profile (1mm) ThinSOT Package supply current and power dissipation advantages over shunt references that must idle the entire load current to operate. Since the LT1790 can also sink current, it can APPLICATIONS operate as a micropower negative voltage reference with n Handheld Instruments the same performance as a positive reference. n Negative Voltage References L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks of Linear n Industrial Control Systems Technology Corporation.
