LM4040 Basic Circuit
Build a basic LM4040 circuit with labeled pins, component values and connection guidance.
Package view
LM4040 in a circuit
TO-92 physical connections, feed resistor and a modest load.
Connect it, step by step
Follow the component values and pin connections
Return
Ground anode3; leave DNC1 floating in this example.
Budget
A 10 kΩ load leaves approximately 754 µA reference current at nominal values.
