APPLICATION NOTES
RECOMMENDED MOUNTING
Optimum performance can only be achieved when the IC
is mounted on a PC board according to the diagram below.
This is because of the extremely small package and limited
power dissipation. Shape the metal portion of the PCB as
shown in the following drawing.

Use a large bypass capacitor and connect it in a place near
GND of the IC. Pay attention to temperature characteristics
of the capacitor, especially the increase of ESR and de-
crease of capacitance in low temperatures. Oscillation,
reduction of ripple rejection and increased noise may occur
in some cases if the proper capacitor is not used. An output
capacitor more than 1.0
μ
F is required to maintain stability.
The standard test condition is 3.3
μ
F (T
A
= 25
°
C).
DROPOUT VOLTAGE
Dropout voltage is the voltage difference between the input
voltage and the output voltage where the output voltage
decreases to 100 mV below the nominal output voltage as
the input voltage is decreased.
To measure dropout voltage, set the input voltage to the
nominal output voltage +1 V and measure the output
voltage. Reduce the input voltage to the point where the
output is 100 mV below the previously measured value.
The dropout voltage is the difference between the input and
output voltage at this point. This voltage depends on the
load current and ambient temperature.
