Functional Description
The TLE 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 TLE 4266, but with a reduced quiescent current of << 1 A in OFF
mode and 40 A in ON mode. The TLE 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 PG-SOT223-4 package. It is pin compatible to the
TLE 4266 G. 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 TLE 4266-2 can be used in
other applications, where a stabilized voltage and the inhibit feature is required.
And input voltage
