Bypass and Load Capacitors
The LT6654 voltage references should have an input by-
pass capacitor of 0.1F or larger, however the bypassing
on other components nearby is sufficient. In high voltage
applications, VIN > 30V, an output short-circuit to ground
can create an input voltage transient that could exceed the
maximum input voltage rating. To prevent this worst-case
condition, an RC input line filter of 10s (i.e. 10 and 1F)
is recommended. These references also require an output
capacitorforstability.Theoptimumoutputcapacitancefor
most applications is 1F, although larger values work as
well. This capacitor affects the turn-on and settling time
for the output to reach its final value.

Figure 1 shows the turn-on time for the LT6654-2.5 with a
0.1F input bypass and 1F load capacitor. Figure 2 shows
the output response to a 0.5V transient on VIN with the
same capacitors.
The test circuit of Figure 3 is used to measure the stability
with various load currents. With RL = 1k, the 1V step pro-
duces a current step of 1mA. Figure 4 shows the response
to a ±0.5mA load. Figure 5 is the output response to a
sourcing step from 4mA to 5mA, and Figure 6 is the output
response of a sinking step from 4mA to 5mA.
