MC7905CT

The MC7905CT is a three-terminal negative voltage regulator manufactured by Motorola Semiconductor. It provides a fixed output voltage of -5V and is suitable for a variety of applications. The device is available in a TO-220 package, designed for through-hole mounting.

Key electrical characteristics include an input voltage range up to -35V, an output current capability of up to 1A, and a dropout voltage of typically 2V. The regulator incorporates internal current limiting, thermal shutdown, and safe operating area compensation, making it highly reliable and essentially indestructible under normal operating conditions.

With an operating temperature range from 0°C to 125°C, the MC7905CT is well-suited for many industrial and commercial applications. Its line and load regulation specifications ensure stable output voltage under varying input and load conditions. The device also offers good ripple rejection, making it effective in power supply applications where noise reduction is important.

The TO-220 package is a standard power package that facilitates heat dissipation, crucial for linear regulators operating at higher power levels. Through-hole mounting makes it easy to integrate into circuit boards using conventional assembly processes.
