Absolute Maximum Ratings
Note: Stresses above those listed in “ABSOLUTE MAXIMUM RATINGS”, may cause permanent
damage to the device. This is a stress only rating and operation of the device at these or any
other conditions above those indicated in the operational sections of this specification is not
implied.

). In
particular, θ
JA
is a function of the PCB construction. The stated number above is for a four-layer board in
accordance with JESD-51 (JEDEC).
Electrical Characteristics
Unless otherwise specified, these specifications apply over VIN = 12V, and T
A
= 0 to 70°C.
Following are the bypass capacitors: C

= 4.7µF, and all X5R ceramic capacitors.
Typical values refer to T
A
= 25°C. Low duty cycle pulse testing is used which keeps junction and
case temperatures equal to the ambient temperature.
