DESCRIPTION
The AIC1714 is 3-terminal negative voltage
regulators, which transform from negative
supply voltage. The high capacity and long
service life of battery, which result from the
characteristics of AIC1714 – low quiescent
current consumed and low dropout voltage
needed, perfectly meet the requirement for
battery-powered portable devices as well as
LCD displays.
The AIC1714 is available in several preset
output voltage versions (-5.0V, -3.3V, and -3.0V)
with short circuit protection and offered in
TO-92
and
SOT-89
packages.

APPLICATION INFORMATION
INPUT-OUTPUT CAPACITORS
The linear regulator requires the output capacitor
to maintain stability. An aluminum electrolytic
output capacitor at 1μF is recommended for most
AIC1714 applications. A 0.1
μF
input capacitor (or
greater) should be placed from the AIC1714 input
to ground if the lead inductance between the
input and the power source exceeds 500nH.
POWER DISSIPATION
The maximum power dissipation of AIC1714
depends on the thermal resistance of its case
and circuit board, the temperature difference
between the die junction and ambient air, and
the rate of airflow. The rate of temperature rise is
greatly affected by the mounting pad
configuration on the PCB, the board material,
and the ambient temperature. When the IC
mounting with good thermal conductivity is used,
the junction temperature will be low even when
large power dissipation applies.
The power dissipation across the device is
P = I
OUT
(V
IN
-V
OUT
).
The maximum power dissipation is:
(T
- T
A
)
P
MAX
=
J-max
Rθ
JA
Where T
J-max
is the maximum allowable junction
temperature (125°C), and T
A
is the ambient
temperature suitable in application.
As a general rule, the lower temperature is, the
better reliability of the device is. So the PCB
mounting pad should provide maximum thermal
conductivity to maintain low device temperature.
