Instructions for LT1086CM

1. Input Voltage (VIN):

   • Ensure the input voltage is within the range of 3.0V to 20.0V.
   • The input capacitor should be placed close to the input pin to minimize noise.

2. Output Voltage (VOUT):

   • The LT1086CM provides a fixed output voltage of 5.0V.
   • Use an output capacitor to stabilize the output and reduce ripple.

3. Output Current (IOUT):

   • The device can supply up to 1.0A continuously.
   • For higher current requirements, consider heatsinking or using a different regulator.

4. Dropout Voltage:

   • Maintain a minimum difference between VIN and VOUT to ensure proper regulation.
   • At full load (1A), the dropout voltage is typically 1.5V.

5. Quiescent Current (IQ):

   • The quiescent current is approximately 5mA at an input voltage of 5V.
   • This value helps in calculating the power dissipation.

6. Power Dissipation (PD):

   • Calculate power dissipation as ( P_D = (V_ - V_) times I_ + V_ times I_Q ).
   • Ensure that the junction temperature does not exceed safe limits by providing adequate heat sinking if necessary.

7. Operating Temperature (TOPR):

   • Operate the device within the temperature range of -40°C to 85°C.
   • Exceeding these temperatures can affect performance and reliability.

8. Installation and Handling:

   • Handle with care to avoid damage to the pins and body.
   • Follow standard PCB assembly practices for optimal performance.

9. Testing:

   • Verify all connections before applying power.
   • Test under various conditions to ensure stability and correct operation.
