General Description
TS4266G is a 5V low-drop fixed-voltage regulator in an SOT-223-4L package. It can be switched ON and OFF by the
Inhibit pin. It is functional and pin compatible to the TS4266, but with a reduced quiescent current of <1uA in OFF mode
and 40uA in ON mode. The TS4266G is especially designed for all applications that require very low quiescent current
in ON and OFF mode. It is designed to supply microprocessor systems under the sever condition of automotive
applications and therefore it is equipped with additional protection against over load, short circuit and over temperature.
TS4266G also can be used in other applications, where a stabilized voltage and the inhibit feature is required. The IC
regulates an input voltage in the range of 5.5V < Vin < 45V to Vout(rated) = 5.0V. The maximum output current is more
than 150mA. This IC is regulated at the inhibit pin pull high level voltage.
