MIC5253-1.85BC5

MIC5253-1.85BC5 Description

The MIC5253-1.85BC5 is a linear voltage regulator from Microchip Technology, part of the Teeny™ series, designed to provide a fixed output voltage of 1.85V with a maximum output current of 100mA. This regulator is optimized for low power consumption, featuring a maximum supply current of 150 µA and a quiescent current of 100 µA. It operates with an input voltage range up to 5.5V and has a dropout voltage of 0.3V at 100mA, ensuring efficient performance even at low input-to-output differentials. The regulator includes protection features such as over-current protection, over-temperature protection, and under-voltage lockout (UVLO) to safeguard against various fault conditions. It also offers an enable control feature for additional flexibility in system design. The MIC5253-1.85BC5 is available in a surface-mount SC70-5 package, making it suitable for compact and space-constrained applications. Despite being marked as obsolete, it remains a reliable choice for specific legacy systems and applications.
