Application Hints
MAXIMUM POWER DISSAIPATION CAPABILITY
Each output pin the LP2967 can deliver a current of up to
150mA over the full operating junction temperature range.
However, the maximum output current must be derated at
higher ambient temperature to ensure the junction tempera-
ture does not exceed 125˚C. Under all possible conditions,
the junction temperatures must be within the range specified
under operating conditions. The LP2967 is available in
MSOP-8 package and 8-bump micro SMD. The junction to

ambient temperature coefficient (θ
age is 235˚C/W and the 8-bump micro SMD with minimum
copper area is 220˚C/W. The total power dissipation of the
device is given by:
The maximum power dissipation, PDmax, that the device
can tolerate can be calculated by using the formula:
