Voltage Reference FAQ

Can the LT1236-10 be used as a shunt regulator?

Yes, the 10V version can function as a shunt regulator (two-terminal zener) with the same precision characteristics as its three-terminal connection.

What is the purpose of the trim pin on the LT1236-10?

The trim pin allows for adjusting the output voltage. It has an impedance of about 12kΩ and is designed to be driven from a source impedance of 3kΩ or less to minimize changes in the temperature coefficient during trimming.
