Instructions for LM317T-DG

1. Pin Configuration:

   • Input (IN): Connect the unregulated input voltage.
   • Output (OUT): Connect this pin to the load and the adjustment resistor network.
   • Adjust (ADJ): Connect this pin to the resistors that set the output voltage.

2. Setting Output Voltage:

   • The output voltage can be adjusted using two external resistors (R1 and R2). The formula to calculate the output voltage is: [ V_ = 1.25 times left(1 + fracright) ]

3. Capacitor Requirements:

   • For stable operation, it's recommended to use a 0.1μF capacitor between the input pin and ground.
   • An optional 10μF capacitor between the output pin and ground can improve transient response.

4. Heat Dissipation:

   • Ensure adequate heat sinking if operating at high current or high dropout voltages to prevent overheating.

5. Protection Features:

   • The device includes internal thermal overload protection and safe area compensation.

6. Mounting Orientation:

   • Mount the component with the heatsink in direct contact with the metal tab for efficient heat dissipation.

7. Storage Conditions:

   • Store in a dry environment, away from moisture and corrosive substances.

8. Handling Precautions:

   • Handle with care to avoid damage to the leads and body of the component.
