DIA7866中文资料40V, 300mA,低功耗线性稳压器数据手册DIOO规格书

描述 Description

The DIA7866 is a low-dropout linear regulator designed for battery-direct-connection automotive applications. The device operations with a wide input voltage ranging from 3 V to 40 V that makes DIA7866 a good fit for severe operating conditions including load dump, cold cranking and start-stop. The low quiescent current and low dropout voltage allow operations at extremely low-power levels. With only 6 µA ultra-low quiescent current at no load, the DIA7866 is quite suitable for microcontrollers and CAN/LIN transceivers power supply in standby systems. The regulator output current is limited internally, and the device is protected against short-circuit, over-load, and over-temperature conditions. The DIA7866 is available in EP-SOIC8 package. It is specified over ambient temperature range of -40°C to 125°C, which meets the requirements of automotive applications.
