Functional Description (Continued)

Thermal Design

The AP1084 incorporates an internal thermal

shutdown that protects the device when the junction

temperature exceeds the maximum allowable

junction temperature. Although this device can

operate with junction temperatures in the range of

150

sink be chosen such that during maximum

continuous load operation the junction temperature

is kept below the temperature.

Layout Consideration

The output capacitors must be located as close to

the Vout terminal of the device as possible. It is

recommended to use a section of a layer of the PC

board as a plane to connect the Vout pin to the

output capacitors to prevent any high frequency

oscillation that may result due to excessive trace

inductance.
