It's a buffer circuit - it provides a high impedance input, and low impedance output with ~ unity gain. If you have a circuit that cannot drive much power, you can use a voltage follower to help. Also, if the input or output of a circuit needs to stay a specific value, such as with filters, you can easily control this due to the isolation the voltage follower provides.
What else can I help you with?
How does the non inverting amplifier differs from voltage follower circuit?
altough voltage follower circuit provides output voltage which is in phase to input voltage as in noninverting amplifier but in unamplified form.
Signal conditioning circuit of potentiometer?
you can use an impedence converter or a voltage follower
What is a voltage follower Op-amp?
It is an amplifier that has no gain or a gain of one mainly used for isolation .
Why emitter follower is used in circuits?
The (Class C, Common Collector) Emitter Follower is used to amplify the available current from a voltage driving circuit that might be disturbed by the load impedance. If the actual voltage value is important, the emitter follower is often teamed up with an opamp which sets the emitter voltage based on the input voltage.
Is the slew rate of the non-inverting amplifier the same as the voltage follower?
It can be but it might not be, it depends on circuit design.

What is a Darlington IC?
Darlington circuit is voltage follower circuit with high input impedance and low output impedance.Darlington IC must have this ciruit integrated on it..
Which transister is used in emitter follower circuit?
A: Any transistor of either polarity can be used as an emitter follower, The purpose of an emitter follower is to provide current to the load since it cannot provide any voltage gain
What is the Primary function of a voltage follower circuit?
Its purpose is to provide approximately the same voltage to a load as what is input to the amplifier, but at a much greater current. In other words, it has no voltage gain, but it does have current gain.
What is the voltage gain of voltage follower?
A: Voltage follower imply that the output will follow the input without any gain.
What is voltage follower?
A voltage buffer amplifier is used to transfer a voltage from a first circuit, having a high output impedance level, to a second circuit with a low input impedance level.If the voltage is transferred unchanged (the voltage gain Av is 1), the amplifier is a unity gain buffer; also known as a voltage follower because the output voltage follows or tracks the input voltage. Although the voltage gain of a voltage buffer amplifier may be (approximately) unity, it usually provides considerable current gain and thus power gain
