Stepdown Voltage Regulator / Adjustable Voltage Regulator IC 1.2v ~ 37v (1.5A) - LM317T

LM317T is an adjustable voltage regulator integrated circuit (IC) that is commonly used in power supply circuits to provide a stable and adjustable output voltage. It is a versatile component that can regulate output voltages in a range of 1.25V to 37V, depending on the external components used with it. Here are the key features and details about the LM317T:
Key Features of LM317T:

* Adjustable Output Voltage: The output voltage can be adjusted from 1.25V to 37V using a pair of external resistors.
* Current Output: Can deliver more than 1.5A of load current.
* Line Regulation: Provides good regulation with changes in the input voltage.
* Load Regulation: Maintains stable output voltage with varying load currents.
* Thermal Overload Protection: Includes built-in protection against overheating.
* Short-Circuit Protection: Protects against short circuits by limiting the current.
* Safe Area Protection: Ensures safe operation by limiting the power dissipation within the IC.

Pin Configuration:

The LM317T typically comes in a TO-220 package with three pins. The pin configuration is as follows:

* Adjust (Adj): This pin is connected to the resistor divider that sets the output voltage.
* Output (Out): This pin provides the regulated output voltage.
* Input (In): This pin accepts the input voltage, which should be higher than the desired output voltage by at least 3V.

Typical Applications:

* Adjustable Power Supplies: Used in laboratory power supplies where a range of output voltages is required.
* Battery Chargers: Regulates charging voltage for batteries.
* Post-Regulation: Provides a stable output voltage in conjunction with switching power supplies.
* Current Regulators: Used in constant current applications, such as LED drivers.
* Embedded Systems: Powers various components in electronic circuits.
