LT1469CN8 Parameter Table

Instructions for Using LT1469CN8

1. Power Supply Connection:

   • Connect the input voltage (VIN) to the appropriate pin.
   • Ensure the input voltage is within the specified range (2.5V to 30V).

2. Output Configuration:

   • Set the output voltage using external resistors for each channel. The formula to calculate the output voltage is: [ V_ = V_ left(1 + fracright) ] where ( V_ ) is typically 1.24V.

3. Bypass Capacitors:

   • Place a 1μF ceramic capacitor close to the input pin (VIN) to filter out noise and improve stability.
   • Place a 1μF ceramic capacitor on each output pin (VOUT1, VOUT2) to ensure stable operation and reduce output ripple.

4. Thermal Considerations:

   • Ensure adequate heat dissipation if operating at high output currents or high ambient temperatures.
   • Use a heatsink if necessary to keep the junction temperature within the specified range (-40°C to 125°C).

5. Shutdown Function:

   • To enable the shutdown function, connect the SHDN pin to ground to turn off the regulators.
   • Connect the SHDN pin to VIN to turn on the regulators.

6. PCB Layout:

   • Keep the layout compact and minimize trace lengths to reduce parasitic inductance and capacitance.
   • Ensure proper grounding and decoupling to maintain stability and performance.

7. Testing and Verification:

   • Test the output voltage and current under various load conditions to ensure the regulators meet the design specifications.
   • Measure the dropout voltage and line/load regulation to verify the performance.

By following these instructions and parameters, you can effectively use the LT1469CN8 in your design.
