current limiting and thermal shutdown making them
user−friendly. Figure 15 is a typical application circuit. The
output capability of the regulator is in excess of 300 mA,
with a typical dropout voltage of less than 260 mV. Internal
protective features include current and thermal limiting.
EXTERNAL CAPACITORS
capacitance between the output and ground for stability for
1.8 V, 2.5 V, 3.0 V, and 3.3 V output voltage options. Output
voltage options of 5.0 V require only 0.22 mF for stability.
The output capacitor must be mounted as close as possible
to the MC33375. If the output capacitor must be mounted
further than two centimeters away from the MC33375, then
a larger value of output capacitor may be required for
stability. A value of 0.68 mF or larger is recommended. Most
type of aluminum, tantalum, or multilayer ceramic will
perform adequately. Solid tantalums or appropriate
multilayer ceramic capacitors are recommended for
operation below 25°C. An input bypass capacitor is
recommended to improve transient response or if the
regulator is connected to the supply input filter with long
wire lengths, more than 4 inches. This will reduce the
circuit’s sensitivity to the input line impedance at high

or other capacitor having low internal impedance at high
frequencies should be chosen. The bypass capacitor should
be mounted with shortest possible lead or track length
directly across the regulator’s input terminals. Figure 16
