Linear regulators require input and output capacitors in order to
maintain over-all loop stability. The recommended minimum
value for the input capacitor is 0.1
μ
F. The output capacitor is
the dominant pole that provides the high-frequency compensa-
tion required for over-all regulator loop stability. These devices
are stable with as little as 1
μ
F. However, to ensure stable
operation under all conditions and capacitor types, the recom-
mended minimum value is 4.7
μ
F. The output capacitor may be
partially distributed through the load circuits. However, at least
1
μ
F should be connected at the regulator using the shortest and
widest foil pattern possible.
Thermal Considerations
These devices are intended to provide up to 100 mA of load
current in a very small package. The table on page 2 of this data
sheet gives the maximum allowable average output current for a
worst-case printed circuit design (R
θ
JA
= 220
°
C/W with a
minimum footprint). Performance improvement is easily
accomplished with the addition of 1 square inch of copper at
terminal 2 (R
θ
JA
= 170
°
C/W).
