LT1461CCS8-3.3#PBF

产品概述

The LT1461CCS8-3.3#PBF is a micropower precision low dropout Voltage Reference Family that combines very high accuracy and low drift with low supply current and high output drive. This series reference use advanced curvature compensation techniques to obtain low temperature coefficient and trimmed precision thin-film resistors to achieve high output accuracy. It draws only 35µA of supply current, making it ideal for low power and portable applications. However, its high 50mA output drive makes it suitable for higher power requirements, such as precision regulators. In low power applications, a dropout voltage of less than 300mV ensures maximum battery life while maintaining full reference performance. 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. It is available in 2.5, 3, 3.3 4.096 and 5V options.
