Peak current into regulator switch (L pin) ........150 mA
Switcher transient peak off voltage on L pin ......+1.0 V
C4–C1, E1, CHCLK,
Maximum power dissipation, (see note) ...... T
Note: Thermal limiting circuitry on chip will shut down the
circuit at a junction temperature of about 165°C. The device
should never be exposed to this temperature. Operation
above 145°C junction temperature may degrade device
reliability. See the SLIC Packaging Considerations for more
information.
Stresses above those listed under Absolute Maximum Ratings
may cause permanent device failure. Functionality at or above
these limits is not implied. Exposure to Absolute Maximum
Ratings for extended periods may affect device reliability.

Operating Ranges define those limits between which the
functionality of the device is guaranteed.
* Functionality of the device from 0 C to +70 C is guaranteed
by production testing. Performance from –40°C to +85°C is
guaranteed by characterization and periodic sampling of
production units.
