APPLICATIONS INFORMATION
Precision Regulator
The LT1460-10 is ideal as a precision regulator, and since
it operates in series mode it does not require a current
setting resistor. The reference can supply up to 20mA of
load current with good transient response. Load regula-
tion at 20mA output is typically 70ppm/mA meaning the
output changes only 14mV.
Capacitive Loads
The LT1460-10 is designed to be stable with capacitive
loads. With no capacitive load, the reference is ideal for
fast settling or applications where PC board space is a
premium. The test circuit shown in Figure 1 is used to
measure the response time for various load currents and
load capacitors. The 1V step from 10V to 9V produces a
