MC7908CT Description

Short technical summary and product information.

The MC7908CT is a linear voltage regulator designed for negative voltage applications. It offers a fixed output voltage of -8V and can deliver an output current of up to 1A. This device is part of the MC7900 series, known for their ruggedness and internal protection features, including current limiting and thermal shutdown.

 

The regulator requires no external components for its basic operation. It is housed in a TO-220 package, suitable for through-hole mounting. The operating temperature range is from 0°C to 125°C. The MC7908CT is designed to complement the popular MC7800 series of positive voltage regulators.

 

Key electrical characteristics include a maximum input voltage of -35V and a typical voltage dropout of 1.1V at 1A. The device also provides a Power Supply Rejection Ratio (PSRR) of 60dB at 120Hz. These features make it suitable for various power management applications where a stable negative voltage is required.
