(1)

See System Characteristics for details of input voltage range.

(2)

Under no conditions should the output voltage be allowed to fall below zero volts.

(3)

An extended output voltage range to 10 V is possible with changes to the typical application schematic. Also, some system

specifications are not achieved for output voltages greater than 6 V. Consult the factory for further information.

(4)

High junction temperatures degrade operating lifetimes. Operating lifetime is de-rated for junction temperatures greater than 125°C.

7.3 Recommended Operating Conditions

over the recommended operating junction temperature range of –40°C to 150°C (unless otherwise noted)

The values given in this table are only valid for comparison with other packages and cannot be used for design purposes. These values

were calculated in accordance with JESD 51-7, and simulated on a 4-layer JEDEC board. They do not represent the performance

obtained in an actual application. For design information please see the Maximum Ambient Temperature section. For more information

about traditional and new thermal metrics, see the Semiconductor and IC Package Thermal Metrics application report and the Using

New Thermal Metrics (SBVA025) application report.
