1 A Three-Terminal Low-Dropout Voltage Regulator
The TA48***BF series consists of fixed-positive-output,
low-dropout regulators with an output current of 1 A (max) that
utilize V-PNP transistors for the output stage. In response to the
need for low-voltage and low-power dissipation devices for use in
consumer electronics and industrial appliances, the series offers
devices with low output voltages:1.5 V, 1.8 V, 2.5 V, 3.3 V, 5 V,
8 V, 9 V

Note 1: Do not apply external current and voltage (including negative voltage) to non-specified pins.
Note 2: 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).

• 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.
Precautions in 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.
