Product Details
Purchasing and Inquiry
The LM317T is a popular voltage regulator integrated circuit (IC) manufactured by various semiconductor companies, including Texas Instruments. It is part of the LM317 series and is widely used in electronic circuits to provide a stable and adjustable output voltage. Here are some key features and information about the LM317T:
Voltage Regulation:
The LM317T is an adjustable three-terminal positive voltage regulator. It is capable of providing a regulated output voltage that can be adjusted between a reference voltage (approximately 1.25 volts) and a maximum specified voltage.
Adjustable Output:
One of the key features of the LM317T is its adjustability. By using external resistors, you can set the output voltage to the desired value within the specified range.
Maximum Output Current:
The LM317T is capable of sourcing a maximum current, which depends on the specific variant and the configuration. Common configurations can provide currents up to 1.5A or more, but this may vary.
Thermal Overload Protection:
The IC includes built-in thermal overload protection. This feature helps prevent the IC from overheating by shutting down the output when the temperature exceeds a certain threshold.
Input Voltage Range:
The input voltage should be higher than the desired output voltage plus the dropout voltage. The dropout voltage is the minimum voltage difference between the input and output required for the regulator to function properly.
TO-220 Package:
The "T" in LM317T indicates the TO-220 package type. This package provides good thermal dissipation, making it suitable for various applications.
Applications:
The LM317T is commonly used in electronic projects where a stable and adjustable voltage supply is required. It's used in power supplies, battery chargers, and various other applications.
Adjustment Pin (ADJ):
The LM317T has an adjustment pin (ADJ) that allows you to set the output voltage by connecting external resistors.
Output Voltage Formula:
When using the LM317T in a circuit, ensure proper heatsinking if higher currents are involved, and refer to the datasheet for detailed specifications, application notes, and example circuits. The LM317T is a versatile component for voltage regulation in a wide range of electronic projects.
