The ILE 4264-2 is a Monolithic Integrated Low Power
Low-Drop Fixed Voltage Regulator 5-V/100mA with low
current consumption. The ILE 4264-2 is specially designed
to create power source with 5V output voltage, loads up to
100 mA and drop voltage less than 0.5V. The regulator is
designed to supply electronic device in automotive
applications and some another applications. The ILE 42642 is equipped with additional protection against overvoltage
of both polarities, load current limitation, short-circuit and
over temperature shutdown of output voltage.

In the ILE4264-2 the output voltage is divided and compared2 to an internal reference of 2.5 V
typical. The regulation loop controls the output to achieve an output
G voltage of 5V with an accuracy
INH
of ±3% at an input voltage range of 6.0 V < VI < 28 V.
Figure shows a typical application circuit. For stability of the control loop the ILE4264-2 output
requires an output capacitor CQ 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 CI, 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).
