The
ILE
4266-2 is a monolithic integrated low-drop fixed voltage regulator which can
supply loads up to 150 mA. It can be switched on and off by the INH pin. It is functional
compatible to the
ILE
4266, but with a reduced quiescent current of < 1
µA
in OFF
mode and 35
µA
in ON mode. The
ILE
4266-2 is especially designed for all applications
that require very low quiescent current in ON and OFF mode. The device is available in
the small surface mounted P-SOT223-4-2 package. In the P-SOT223-4-2
housing it is pin compatible to the
ILE
4266G. It is designed to supply
microprocessor systems under the severe condition of automotive applications and
therefore it is equipped with additional protection against over load, short circuit and
overtemperature. Of course the
ILE
4266-2 can be used in other applications, where a
stabilized voltage and the inhibit feature is required.
And input voltage
V
I
in the range of
6
V <
V
I
< 45 V is regulated to
V
Q
= 5 V with an
accuracy of
±
3%.
The device operates in the temperature range of
T
j
= – 40 to 125
°C.
A High level at the
INH pin switches the regulator on.
