78M05 Voltage Regulator IC | 5V Fixed Linear Regulator – TO-252 DPAK

The 78M05 is a monolithic 5V fixed linear voltage regulator IC designed to provide a stable and regulated output for a wide range of electronic circuits. Packaged in a compact TO-252 (DPAK) SMD package, it can deliver over 0.5A of continuous current while maintaining reliable performance with excellent line and load regulation.

With a maximum input voltage of 35V and a typical dropout voltage of 2V, the 78M05 is ideal for powering microcontrollers, digital logic, sensors, and embedded systems. Built-in features such as internal current limiting, thermal shutdown, and safe-area compensation ensure rugged operation and long-term reliability even under overload or fault conditions.

The 78M05 is widely used in switching power supplies, consumer electronics, automotive circuits, and general-purpose regulated power rails requiring a clean 5V output.
