Instructions for LT1085CM#PBF:

1. Input Capacitor:

   • It is recommended to use a 0.1μF capacitor between the input pin and ground to stabilize the input voltage.

2. Output Capacitor:

   • Use a minimum of 1μF capacitor between the output pin and ground to ensure stability. Larger values can be used to reduce output noise.

3. Thermal Considerations:

   • Ensure adequate heat sinking if operating near maximum output current, especially in high ambient temperatures.

4. PCB Layout:

   • Keep the input and output capacitors as close as possible to the respective pins to minimize noise and improve transient response.

5. Voltage Setting:

   • For adjustable versions, use a resistor divider network between the output and adjust pins to set the desired output voltage.

6. Short-Circuit Protection:

   • The device includes internal short-circuit protection, but external fuses may be required for robust applications.

7. Storage Conditions:

   • Store in a dry environment to prevent damage due to moisture. Follow standard ESD handling procedures.

8. Package Information:

   • The LT1085CM#PBF comes in a TO-220 package, suitable for through-hole mounting.
