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).
