7805 5V Fixed Voltage Regulator, Through Hole, 100mA

The STMICROELECTRONICS 7805 is a robust three-terminal positive voltage regulator designed to provide a stable 5V DC output from a higher input voltage. It employs internal current limiting and thermal shutdown protection, making it a highly reliable and essentially indestructible component for a wide range of electronic applications. With an adequate heat sink, this regulator can deliver output currents of up to 100 mA.

Its primary function is as a fixed voltage regulator, ideal for local or on-card regulation. This design helps eliminate noise and distribution problems commonly associated with single-point regulation in larger systems, ensuring clean and stable power delivery to sensitive circuits. Additionally, it can be used in conjunction with external power pass elements to construct high-current voltage regulator circuits, offering great design flexibility.

A significant advantage of the 7805 series is its simplicity; no external components are required for basic operation, making it perfect for prototypes, educational projects, and straightforward power supply designs. Its through-hole mounting style ensures easy soldering and secure placement on printed circuit boards (PCBs).
