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

The St MicroElectronics 7805 Voltage Regulator is a fixed 5V, 1.5A positive 3-terminal regulator supplied in a D2PAK-3 package.

This regulator provides stable, on-card voltage regulation. Local regulation avoids the voltage drops that can occur with single-point regulation in a circuit, helping to maintain consistent performance for sensitive components.

Key Features & Protections

• Thermal Overload Protection: Shuts the device down if the junction temperature exceeds safe limits, helping to prevent overheating damage.
• Short-Circuit Protection: Safeguards the IC against output short circuits.
• Output Transition SOA Protection: Helps keep the device within its safe operating area during output transients.
• Tight Voltage Tolerance: Provides a 2% output voltage tolerance.
• Wide Temperature Range: Operates across an extended temperature range from -40°C to 125°C.

Output Capability

With adequate heat sinking, the regulator can deliver output currents exceeding 1A. Although it is engineered as a fixed 5V regulator, external components can be added to create adjustable voltage and current supplies, offering flexibility for a range of circuit designs.

Applications

The regulator is suited to power management tasks in a wide range of electronic devices. It can be used to provide clean, stable 5V power to microcontrollers, sensors and digital logic ICs.
