线性技术Corporation announces a new wider temperature range, H grade version of the LT3007, the latest member in a family of high voltage, micropower, robust PNP-based LDOs, featuring an ultralow 3µA quiescent current. The device’s H grade 150°C junction temperature rating enables high temperature or high power automotive and industrial applications. Its high input voltage capability, spanning 2.0V to 45V with an adjustable output voltage ranging from 0.6V to 44.5V, enables operation in a wide range of applications. The LT3007’s pinout is FMEA (Failure Mode Effects Analysis) compliant, so the output stays at or below the regulation voltage during an adjacent pin short event, or if a pin is left floating. The device’s 3µA quiescent and shutdown currents (<1µA) enable ultralow standby power consumption, making the IC ideal for applications not requiring shutdown, or those needing moderate output drive capability and high input voltage, such as remote monitoring and low-current battery-powered memory for “keep alive” systems requiring extended run times.
LT3007可提供高达20mA的输出电流，相应的低压差电压仅为300mV。输出电压容差在线，负载和温度紧密地调节到±2％以内。该IC优化低ESR，陶瓷输出电容小于2.2μF的稳定性和瞬态响应。内部保护电路包括反向电池保护，反向输出和反向输出到输入保护，电流限制和鲁棒性的热限制。
在8引脚SOT-23封装中提供的LT3007在E，I和H级别中提供，其中3个引脚熔合到接地桨，以提高固定和可调版本的热性能。1,000件式定价以1.20美元的价格为1.20美元，为H级的E级和1.75。
