TC1016
4.1
Low input source impedance is necessary for the LDO
to operate properly. When operating from batteries, or
in applications with long lead length (> 10") between
the input source and the LDO, some input capacitance
is required. A minimum of 0.1 µF is recommended for
most applications and the capacitor should be placed
as close to the input of the LDO as is practical. Larger
input capacitors will help reduce the input impedance
and further reduce any high-frequency noise on the
input and output of the LDO.
4.2
A minimum output capacitance of 1 µF for the TC1016
is required for stability. The ESR requirements on the
output capacitor are between 0 and 2 ohms. The output
capacitor should be located as close to the LDO output
as is practical. Ceramic materials X7R and X5R have
low temperature coefficients and are well within the
acceptable ESR range required. A typical 1 µF X5R
0805 capacitor has an ESR of 50 milli-ohms. Larger
output capacitors can be used with the TC1016 to
improve dynamic behavior and input ripple rejection
performance.
Ceramic, aluminum electrolytic or tantalum capacitor
types can be used. Since many aluminum electrolytic
capacitors freeze at approximately –30 C, ceramic or
solid tantalums are recommended for applications
operating below –25 C. When operating from sources
other than batteries, supply noise rejection and tran-
sient response can be improved by increasing the
value of the input and output capacitors, and by
employing passive filtering techniques.
