Figure 2 shows the response of the reference with no load
capacitance.
The reference settles to 10mV (0.1%) in 0.4
μ
s for a 100
μ
A
pulse and to 0.1% in 0.8
μ
s with a 1mA step. When load
capacitance is greater than 0.01
μ
F, the reference begins to
ring due to the pole formed with the output impedance.

Fast Turn-On
It is recommended to add a 0.1
μ
F or larger input capacitor
to the input pin of the LT1460-10. This helps stability with
large load currents and speeds up turn-on. The LT1460-10
can start in 10
μ
s, but it is important to limit the dv/dt of the
input. Under light load conditions and with a very fast
input, internal nodes overslew and this requires finite
recovery time. Figure 4 shows the result of no bypass
capacitance on the input and no output load. In this case
the supply dv/dt is 12.5V in 30ns which causes internal
overslew, and the output does not bias to 10V until 60
μ
s.
A 0.1
μ
F input capacitor guarantees the part always starts
quickly as shown in Figure 5.
