This series reference uses advanced curvature pensation techniques to obtain low temperature coefficient and trimmed precision thin-film resistors to achieve high output accuracy. The LT1461 draws only 35µA of supply current, making it ideal for low power and portable applications, however its high 50m A output drive makes it suitable for higher power requirements, such as precision regulators. In low power applications, a dropout voltage of less than 300m V ensures maximum battery life while maintaining full reference performance. Line regulation is nearly immeasurable, while the exceedingly good load and thermal regulation will not add significantly to system error budgets. The shutdown feature can be used to switch full load currents and can be used for system power down. Thermal shutdown protects the part from overload conditions. , LTC and LT are registered trademarks of Linear Technology Corporation.
