Load Regulation

Since the EP1084 is only a 3 terminal device, it is not possible to provide true remote sensing of the

output voltage at the load. The best load regulation is achieved when the bottom side of R2 is connected

regulator and not to the load. It is important to note that for high current applications, this can re-present

a significant percentage of the overall load regulation and one must keep the path from the regulator to

the load as short as possible to minimize this effect.

Stability

The EP1084 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 10uF aluminum electrolytic capacitor

insures both stability and good transient response.

Thermal Design

The EP1084 incorporates an internal thermal shutdown that protects the device when the junction

temperature exceeds the maximum allowable junction temperature. Although this device can operate

chosen such that during maximum continuous load operation the junction temperature is kept below the

temperature.

Layout Consideration

output capacitors to prevent any high frequency oscillation that may result due to excessive trace

inductance.
