The onsemi KA78RM33 is a positive, fixed output linear voltage regulator IC. This component delivers a stable 3.3V output with a maximum current capability of 500mA. Designed for through-hole mounting in a TO-220-3 package, it offers a low dropout voltage of 0.6V at 500mA, ensuring efficient operation even with minimal input voltage headroom. Key protection features include over-current, over-temperature, and short-circuit protection. The device operates within a temperature range of -40°C to 125°C and has a typical quiescent current of 5mA. It is suitable for a wide array of applications, including automotive systems, industrial power supplies, and consumer electronics. The output configuration is positive, and the input voltage can be as high as 20V.
