STMicroelectronics 7805 Linear Voltage Regulator 5V 0.5A TO-252-3

The STMicroelectronics 7805 Linear Voltage Regulator is a three-terminal positive voltage regulator designed to provide a stable and fixed 5V output. Accepting an input voltage range from 10V to 35V, it is suitable for a wide variety of power management applications. This device provides local on-card regulation, which effectively eliminates the distribution issues commonly associated with single-point regulation systems.

Equipped with comprehensive internal safety features, this regulator includes internal current limiting, thermal shutdown, and safe operating area (SOA) protection. These integrated safeguards make the component highly robust and reliable in demanding environments. When used with adequate heat sinking, it can deliver an output current of up to 0.5A (500mA). Although primarily designed as a fixed voltage regulator, it can also be configured with external components to achieve adjustable voltages and currents, adding to its versatility.

Key Features and Protection

• Fixed output voltage of 5V with a 4% tolerance
• Thermal overload protection
• Short-circuit protection
• Output transition safe operating area (SOA) protection
