it will limit the load regulation.
Figure 6 to Figure 8 illustrate response in the LT1460-5.
The 1V step from 5V to 4V produces a current step of
1mA or 100µA for R
response of the reference with no load capacitance.
The reference settles to 5mV (0.1%) in less than 2µs for
a 100µA pulse and to 0.1% in 3µs with a 1mA step. When
load capacitance is greater than 0.01µF , the reference begins
to ring due to the pole formed with the output impedance.
Figure 8 shows the response of the reference to a 1mA

Figure 9 to Figure 11 illustrate response of the LT1460-10.
The 1V step from 10V to 9V produces a current step of

the response of the reference with no load capacitance.
The reference settles to 10mV (0.1%) in 0.4µs for a 100µA
pulse and to 0.1% in 0.8µs with a 1mA step. When load
capacitance is greater than 0.01µF , the reference begins
to ring due to the pole formed with the output impedance.
Figure 11 shows the response of the reference to a 1mA and
100µA load current step with a 0.01µF load capacitor.
