The LM2576S-ADJ is available in a TO-263 surface-mount package, also known as the D2PAK. This package type is designed for efficient thermal performance and is suitable for applications that require a robust and reliable power supply solution with adjustable output.

The LM2576S-ADJ is a popular step-down voltage regulator with an adjustable output. It typically comes in a 5-pin TO-263 surface mount package. Here’s a brief overview of its pin configuration and functions:
1. VIN (Pin 1): This is the input pin where the unregulated DC voltage is applied. The LM2576S-ADJ can handle input voltages up to 40V.
2. VOUT (Pin 2): This is the output pin that provides the regulated DC voltage. The output voltage can be adjusted using an external resistor divider network.
3. GND (Pin 3): This pin is connected to the ground reference for both the input and output voltages.
4. FB (Pin 4): The feedback pin is used to set the output voltage. It connects to the midpoint of an external resistor divider network connected from VOUT to GND, which determines the output voltage level.
5. ON/OFF (Pin 5): This pin is used for the enable/disable function. Connecting this pin to a low voltage (typically below 1.3V) disables the regulator, while connecting it to a high voltage (typically above 2.2V) enables it.
