ON Semiconductor 7805 +5V Linear Voltage Regulator SMD 1A

The ON Semiconductor 7805 is a monolithic, fixed-voltage linear regulator integrated circuit designed for a broad range of local, on-card regulation applications. It delivers a stable +5.0V DC output with a typical accuracy of 1.5%, 2%, or 4% tolerance, ensuring reliable power for sensitive electronic components.

Engineered for robustness, this regulator incorporates critical internal protection features including short-circuit current limiting, output transistor safe-area compensation, and thermal overload protection. This built-in safety suite enhances the durability and reliability of your circuits. When paired with adequate heat sinking, the device can deliver output currents in excess of 1.0 A.

While primarily designed as a fixed-voltage regulator, the IC is versatile and can be configured with external components to create adjustable voltage and current supplies, offering flexibility for more advanced design requirements. Its surface-mount (SMD) package ensures a compact footprint for modern PCB designs.
