STMICROELECTRONICS 7805 Voltage Regulator, Fixed 5V, 1.5A, D2PAK-3

The STMICROELECTRONICS 7805 Voltage Regulator is a robust 3-terminal positive regulator IC designed to provide stable, on-card voltage regulation. This local regulation eliminates the challenges and potential voltage drops associated with single-point regulation in a circuit, ensuring consistent performance for sensitive components. The device integrates comprehensive protection features, including internal current limiting, thermal shutdown, and safe operating area (SOA) protection, making it an exceptionally durable and resilient component suitable for demanding applications.

With adequate heat sinking, this regulator can reliably deliver output currents exceeding 1A. While engineered as a fixed 5V regulator, its versatile design allows it to be used with external components to create adjustable voltage and current supplies, offering flexibility for various circuit designs. Its built-in safeguards provide peace of mind, protecting both the regulator and the broader circuit from common failure modes.

Key Features & Protections

• Thermal Overload Protection: Automatically shuts down the device if the junction temperature exceeds safe limits, preventing damage from overheating.
• Short-Circuit Protection: Safeguards the IC against output short circuits, a common cause of component failure.
• Output Transition SOA Protection: Ensures the device remains within its safe operating area during output transients.
• Tight Voltage Tolerance: Maintains a precise 2% output voltage tolerance for reliable and consistent performance.
• Wide Temperature Range: Guaranteed operation across an extended temperature range from -40°C to 125°C.

Applications

This regulator is ideally suited for Power Management tasks in a vast array of electronic devices. Its reliability makes it perfect for providing clean, stable 5V power to microcontrollers, sensors, digital logic IC
