Instructions for TLV431AID

1. Circuit Configuration:

   • The TLV431AID can be used as a precision voltage reference or adjustable shunt regulator.
   • Connect the cathode (K) to the output voltage node, and the anode (A) to ground or the lower potential.
   • Use a resistor between the control (C) pin and the cathode to set the desired output voltage.

2. Setting Output Voltage:

   • The output voltage is determined by the resistor ratio connected between the control pin and the cathode.
   • Formula: ( V_ = V_ left(1 + fracright) )
     • Where ( R_1 ) is the resistor from the control pin to ground, and ( R_2 ) is the resistor from the control pin to the cathode.

3. Power Dissipation:

   • Ensure that the power dissipation does not exceed 375mW to avoid overheating.
   • Calculate power dissipation using ( P_d = I_k times (V_k - V_a) ).

4. Temperature Considerations:

   • Operate within the specified junction temperature range (-40°C to 125°C).
   • Store in environments where temperatures do not exceed -65°C to 150°C.

5. Handling Precautions:

   • Handle with care to prevent electrostatic discharge (ESD) damage.
   • Follow standard ESD handling procedures when installing or testing the device.

6. Mounting and Layout:

   • Ensure proper heat sinking if operating near maximum power dissipation.
   • Keep leads short to minimize parasitic inductance and improve stability.
