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).

Electrical Characteristics Common to All Products
• Tj = 25°C in the measurement conditions of each item is the standard condition when a pulse test is carried
out, and any drift in the electrical characteristic due to a rise in the junction temperature of the chip may be
disregarded.

• Be sure to connect a capacitor near the input terminal and output terminal between both terminals and GND.
The use of a monolithic ceramic capacitor (B Characteristic or X7R) of low ESR (equivalent series resistance)
is recommended. The IC may oscillate due to external conditions (output current, temperature, or the type of
the capacitor used). The type of capacitor required must be determined by the actual application circuit in
which the IC is used.
The notice in case of application
• The IC might be destroyed if a voltage greater than the input terminal voltage is applied to the output
terminal, or if the input terminal is connected to GND during operation. To prevent such an occurrence,
connect a diode as in the following diagram.

• There is a possibility that internal parasitic devices may be generated when momentary transients cause a
terminal’s potential to fall below that of the GND terminal. In such case, that the device could be destroyed.
The voltage of each terminal and any state must therefore never fall below the GND potential.
• Depending on the load conditions, a steep increase in the input voltage applied (VIN) may cause a momentary
rise in output voltage (VOUT) even if the EN (enable) pin is Low. Treat with care.
