CL = 1F. RS should not be made arbitrarily large because
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 100A for RL = 1k or RL = 10k. Figure 7 shows the
response of the reference with no load capacitance.
The reference settles to 5mV (0.1%) in less than 2s for
a 100A pulse and to 0.1% in 3s with a 1mA step. When
loadcapacitanceisgreaterthan0.01F,thereferencebegins
to ring due to the pole formed with the output impedance.
Figure 8 shows the response of the reference to a 1mA

and 100A load current step with a 0.01F load capacitor.
Figure 9 to Figure 11 illustrate response of the LT1460-10.
The 1V step from 10V to 9V produces a current step of
1mA or 100A for RL = 1k or RL = 10k. Figure 10 shows
the response of the reference with no load capacitance.
The reference settles to 10mV (0.1%) in 0.4s for a 100A
pulse and to 0.1% in 0.8s with a 1mA step. When load
capacitance is greater than 0.01F, the reference begins
to ring due to the pole formed with the output impedance.
