Figure shows a typical application circuit. For stability of the control loop the ILE4264-2 output

requires an output capacitor

of at least 10 μF with a maximum permissible ESR of 4Ω.

Tantalum as well as multi layer ceramic capacitors are suitable.

At the input of the regulator an input capacitor is necessary for compensating line influences

(100nF ceramic capacitor recommended). A resistor of approx. 1Ω in series with

C

I

, can damp any

oscillation occurring due the input inductivity and the input capacitor.

In the application circuit shown in Figure an additional electrolytic input capacitor of 470 μF is

added in order to buffer supply line influences. This capacitor is recommended, if the device is

sourced via long supply lines of several meters.

The ILE4264-2 can supply up to 150 mA. However for protection for high input voltage above 25 V,

the output current is reduced (SOA protection).
