The MCP1754/MCP1754S is a 16 volt, high PSRR voltage regulator with short circuit current foldback. The MCP1754/MCP1754S regulator provides up to 150 mA of current. The input operating voltage range is specified from 3.6V to 16V continuous, 18V absolute maximum, making it ideal for automotive and commercial 12 VDC systems. The MCP1754/MCP1754S typically delivers 72 dB of ripple rejection at 1 kHz, performing well in AC sensitive applications like GFCI and AFCI circuit breaker designs. The Current Foldback feature is a true short circuit current foldback: the device current will gradually drop to 30 mA under short circuit conditions. When the short is removed, the device will recover and continue operating.
Microchip has developed the Residential Solar Breaker Reference Design featuring the HV9901, as an example reference breaker solution for single phase residential solar installations. All the Reference Design components, including the HV9901, are rated to 125°C, a critical feature for these systems as they are required to operate in the high temperature environment of the solar panel....
