The 78M05A is a low-power, fixed +5V positive linear voltage regulator IC, part of the popular 78xx series, used to provide stable DC power for electronics like microcontrollers, sensors, and digital logic by converting an unregulated input voltage (e.g., 7-35V) into a steady 5V, offering built-in protection like thermal shutdown and overcurrent limiting for reliability in small, battery-powered, or hobbyist projects.
Key Characteristics:
Output Voltage: +5V (fixed).
Output Current: Capable of delivering up to 500mA (with proper heatsinking).
Type: Three-terminal positive voltage regulator (Input, Ground, Output).
Protection Features: Internal current limiting, thermal shutdown, and safe-area compensation.
Packaging: TO-220F
