DIO7875

The DIA7875 is a low-dropout linear regulator designed to function with a wide input voltage range from 3 V to 40 V. The 3 V minimum operation voltage allows DIA7875 to function normally during cold-crank and start and stop conditions. With only 4 µA ultra-low quiescent current at no load, the DIA7875 is quite suitable for microcontrollers and CAN/LIN transceivers power supply in standby systems. The DIA7875 integrates short-circuit and overcurrent protection. The device operates in ambient temperatures from -40°C to 125°C and with junction temperatures from -40°C to 150°C, which enables the DIA7875 to be used in the harsh automotive environment. This device uses a thermally conductive package to enable sustained operation despite significant dissipation across the device.
