AX1008

possible to minimize this effect.

Stability

The AX1008 requires the use of an output capacitor as part of the frequency

compensation in order to make the regulator stable. For most applications a minimum of

100uF aluminum electrolytic capacitor or 10uF MLCC insures stability .

Thermal Design

The AX1008 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 150oC, it is recommended

that the selected heat 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.
