Texas Instruments UA7812 Voltage Regulator

The Texas Instruments UA7812 is a fixed-voltage integrated-circuit voltage regulator designed to offer thermal, short-circuit, and safe-area protection, which makes it essentially indestructible. This regulator can deliver over 1A of output current with a dropout voltage of typically 2V at full load. The device has been engineered to minimize the number of external components, thereby simplifying the power supply design and providing ease of use to the end-user.

Key Features:

• Output Voltage: Fixed at 12V with a precision of 2% at 25°C, and 4% in the full temperature range.
• Output Current: Capable of delivering up to 1.5A of continuous current.
• Thermal Overload Protection: The internal circuitry automatically shuts down the output if the maximum operating temperature is exceeded.
• Short Circuit Protection: Provides internal current limiting to protect the device in the event of a short circuit.
• Safe-Area Compensation: The regulator is internally compensated to prevent instantaneous short-circuit current levels that could otherwise exceed its rated limits.
• No External Components Required: Offers a simple two-pin setup for basic operations, reducing the need for additional external circuitry.

Applications:

The UA7812 is versatile and can be used in a variety of applications that require a regulated 12V supply. Common applications include:

• Linear power supplies
• Battery chargers
• On-board regulation for consumer electronics
• Motor control systems

Product Specifications:

With its robust design and reliable performance, the Texas Instruments UA7812 is an excellent choice for applications requiring a stable and protected 12V power supply.
