equation:
Substituting P
operating conditions that are critical to the ap-
plication will give the maximum operating con-
ditions for the regulator circuit. For example, if
we are operating the SP6201- 3.0V at room
temperature, with a SOT-23-5 package on a 4
layer standard board we can determine the maxi-
mum input voltage for a set output current.
To prevent the device from entering thermal
shutdown, maximum power dissipation can not
be exceeded. Using the output voltage of 3.0V
and an output current of 200 mA, the maximum
input voltage can be determined. Ground pin
current can be taken from the electrical spec’s-
table (I
mum input voltage is determined as follows:
Solving for V
After calculations, we find that the maximum
input voltage of a 3.0V application at 200mA of
output current in an SOT-23-5 package is 5.59V.
Dual-Supply Operation
When used in dual supply systems where the
regulator load is returned to a negative supply,
the output voltage must be diode clamped to
ground.
