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.
