The SPX1117R-L/TR is a low dropout positive voltage regulator manufactured by Sipex Corporation. Similar to the SPX1117R/TR, it provides a stable and regulated output voltage even with a small difference between the input and output voltages. The '-L' likely refers to a lower dropout voltage or a different voltage option. The '/TR' suffix indicates tape and reel packaging.

Applications:

• Battery Powered Systems: Provides stable voltage regulation in battery-operated devices.
• Post Regulation for Switching Supplies: Reduces ripple and noise in switching power supplies.
• Linear Regulation in Industrial Equipment: Provides stable voltage in industrial applications.
• Laptop Computers: Powers various components within laptop computers.

Additional Details:

The SPX1117R-L/TR is available in surface mount packages, such as SOT-223. It typically requires input and output capacitors for stability. The output voltage can be adjusted using external resistors. Internal current limiting and thermal shutdown protect the device from overcurrent and overheating. The '-L' designation likely signifies a lower dropout voltage specification compared to standard SPX1117R versions, enabling more efficient operation when the input voltage is close to the desired output. This characteristic is especially beneficial in battery-powered applications. The '/TR' suffix means the device is supplied on tape and reel, suited for automated manufacturing. The wide operating temperature range makes it suitable for various environments.
