Instructions for Use:

1. Power Supply:

   • Ensure the power supply voltage is within the operating range specified in the absolute maximum ratings.
   • The device should not exceed the maximum power dissipation to avoid thermal damage.

2. Reference Voltage Configuration:

   • Connect the reference pin to a stable voltage source or use it in conjunction with resistors to set the desired output voltage.
   • The typical reference voltage (VREF) is 2.5V.

3. Output Current Handling:

   • The TLV431TFTA can provide up to 100mA of output current. Ensure external components and loads do not exceed this limit.

4. Thermal Management:

   • Monitor the junction temperature to ensure it stays within the -40°C to 125°C range.
   • If operating near the maximum temperature, consider adding heatsinks or improving airflow around the component.

5. Storage and Handling:

   • Store the device in environments where the temperature does not fall below -65°C or rise above 150°C.
   • Handle with care to avoid electrostatic discharge (ESD), which can damage sensitive electronic components.

6. Leakage Current Consideration:

   • Account for a leakage current of up to 1μA when designing circuits to ensure accurate performance.

7. Thermal Resistance:

   • The thermal resistance from junction to ambient (RθJA) is 215°C/W. Design the PCB layout and cooling solutions considering this value to manage heat effectively.
