APPLICATIONS INFORMATION
LT3021/LT3021-1.2/
LT3021-1.5/LT3021-1.8
If the LT3021 is powered by a battery mounted in close
proximity on the same circuit board, a 3.3μF input capacitor
is suffi cient for stability. However, if the LT3021 is powered
by a distant supply, use a larger value input capacitor fol-
lowing the guideline of roughly 1μF (in addition to the 3.3μF
minimum) per 8 inches of wire length. As power supply
output impedance may vary, the minimum input capaci-
tance needed to stabilize the application may also vary.

Extra capacitance may also be placed directly on the output
of the power supply; however, this will require an order of
magnitude more capacitance as opposed to placing extra
capacitance in close proximity to the LT3021. Furthermore,
series resistance may be placed between the supply and
the input of the LT3021 to stabilize the application; as little
as 0.1Ω to 0.5Ω will suffi ce.
