LT1461 Micropower Precision Low Dropout Series Voltage Reference Family FEATURES DESCRIPTION n Trimmed to High Accuracy: 0.04% Max The LT 1461 is a family of low dropout micropower band- n Low Drift: 3ppm/C Max gap references that combine very high accuracy and low n Low Supply Current: 50A Max drift with low supply current and high output drive. These n High Output Current: 50mA Min series references use advanced curvature compensation n Low Dropout Voltage: 300mV Max techniques to obtain low temperature coefficient and n Excellent Thermal Regulation trimmed precision thin-film resistors to achieve high n Power Shutdown output accuracy. The LT1461 family draws only 35A n Thermal Limiting of supply current, making them ideal for low power and n All Parts Guaranteed Functional from 40C to 125C portable applications, however their high 50mA output n Voltage Options: 2.5V, 3V, 3.3V, 4.096V and 5V drive makes them suitable for higher power requirements, n AEC-Q100 Qualified for Automotive Applications such as precision regulators. In low power applications, a dropout voltage of less than 300mV ensures maximum battery life while maintaining APPLICATIONS full reference performance. Line regulation is nearly im- n A/D and D/A Converters measurable, while the exceedingly good load and ther- n Precision Regulators mal regulation will not add significantly to system error n Handheld Instruments budgets. The shutdown feature can be used to switch full n Power Supplies load currents and can be used for system power down. Thermal shutdown protects the part from overload condi- tions. The LT1461 is available in 2.5V, 3V, 3.3V 4.096V and 5V options. All registered trademarks and trademarks are the property of their respective owners.
