Three-Terminal Low Dropout Voltage Regulator with Output Current of 1 A


The TA48**F/S 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 which are
used in consumer electronics and industrial appliances, the series
offers devices with low output voltages: 1.8 V, 2 V, 2.5 V, 3 V, 3.3
V, 5 V.

Electrical Characteristics for All Products
Generally, the characteristics of power supply ICs change according to temperature fluctuations.
The specification T
j
= 25 is based on a state where temperature increase has no effect (assuming no fluctuation
in the characteristics) as ascertained by pulse tests.
Standard Application Circuit

Be sure to connect a capacitor near the input terminal and output terminal between both terminals and GND.
The capacitances should be determined experimentally. In particular, adequate investigation should be made so
that there is no problem even in high or low temperature.
