1A Output Current and Low Dropout Voltage Regulator with ON/OFF Control Switch
The TA48S***AF series consists of small-surface mount type
low-dropout regulators with an output current of 1 A (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).
