300 mA Output Current and Low Dropout Voltage Regulator with ON/OFF Control Switch
The TA48LS***F series consists of small-surface mount type
low-dropout regulators with an output current of 300mA
(maximum) and an ON/OFF control switch. Control by an EN
(ON/OFF) terminal enables the regulator to be operated only
when required (output ON).
Therefore these newly developed regulators are suitable for use
in the power supply circuits of AV, OA and other digital devices
equipped with a stand-by function, and of battery-operated
portable data devices of various types, where they will contribute
to energy saving. Moreover, the regulators have an output
voltage line-up starting from 1.5V, corresponding to the lower
voltage of various devices.

Note 3: Do not apply current and voltage (including reverse polarity) to any pin that is not specified.
Note 4: Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the
significant change in temperature, etc.) may cause this product to decrease in the reliability significantly
even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute
maximum ratings and the operating ranges.
Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook
(“Handling Precautions”/Derating Concept and Methods) and individual reliability data (i.e. reliability test
report and estimated failure rate, etc).
