If T Jmax is internally limited to 150 C, then the MC33263
can dissipate up to 595 mW @ 25 C.
from the following formula:

is extracted from the data–sheet curves: 6.5 mA @ 150 mA.
For a MC33263NW28R2 (2.8 V), the maximum input
voltage will then be 6.48 V, a rather comfortable margin.

taken when tackling Printed Circuit Board (PCB) layout.
The following figure gives an example of a layout where
stray inductances/capacitances are minimized.
Input
The power dissipated by the MC33263 can be calculated
If a 150 mA output current is needed, the ground current
