STMicroelectronics L7812 12V 1.5A Linear Voltage Regulator, TO-263-3

The STMicroelectronics L7812CD2T-TR is a robust 1.5A, 3-terminal positive linear voltage regulator designed to provide stable, local on-card regulation. This eliminates the challenges associated with single-point power distribution, ensuring consistent voltage delivery directly where it's needed on your circuit board.

Engineered for reliability, this IC incorporates comprehensive internal protection features including current limiting, thermal shut-down, and safe operating area (SOA) protection. These integrated safeguards make the regulator highly resilient and essentially indestructible under normal operating conditions. When paired with adequate heat sinking, it is capable of delivering output currents in excess of 1 ampere.

While primarily configured as a fixed 12V output regulator, the device offers design flexibility and can be used with external components to create adjustable voltage and current supplies, expanding its utility in various prototyping and production applications.

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 regulator and your circuit in the event of an output short.
• Output Transition SOA Protection: Ensures the device remains within its safe operating area during output transients.
• Tight Voltage Tolerance: Provides a guaranteed output voltage tolerance of 2%, ensuring precision and stability for sensitive components.
• Extended Temperature Range: Performance is guaranteed across a wide operating temperature range, suitable for demanding environments.

Presented in a surface-mount TO-263-3 (D²PAK) package, this regulator is built for high-power applications where efficient heat dissipation through the package tab is crucial for optimal performance.
