CYT6
167
Application Hints
Like any Low dropout regulator,
CYT6
167 requires
external capacitors to ensure stability. The external
capacitors must be carefully selected to ensure the
performances.
Input Capacitor:
An Input Capacitor of at least 2.2uF is required.
Ceramic or Tantalum can be used. The value can
be increased without upper limit.
Output Capacitor:
An Output Capacitor is required for look stability. It
must be located no more than 1cm away from the
V
OUT
pin, and connected directly between V
OUT
and
GND pins. The minimum value is 2.2uF but once
again its value can be increased without limit.
Thermal Consideration
It is important that the thermal limit of the package
should not be exceeded. The
CYT6
167 has built-in
thermal protection. When the thermal limit is
exceeded, the IC will enter protection, and the V
OUT
will be reset to zero. The power dissipation for a
given application can be calculated as follows:
The Power Dissipation (P
D
) is
P
D
= I
OUT
* [V
IN
– V
OUT
]
The thermal limit of the package is then limited to
P
D(MAX)
= [T
J
– T
A
]/
θ
JA
where T
J
is the junction
temperature, T
A
is ambient temperature, and
θ
JA
is
around 250°C/W for
CYT6
167.
CYT6
167
is designed
to enter thermal protection at 150°C. For example, if
T
A
is 25°C then the max P
D
is limited to about 0.5W.
In other words, if I
OUT(MAX)
= 400mA, then [V
IN
–
V
OUT
] can not exceed 1.25V.
