1.8 V, 2 V, 2.5 V, 3 V, 3.3 V, 5 V 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.
Features
Maximum output current: 1 A Output voltage accuracy: VOUT ± 3% (@Tj = 25°C) Low standby current: 800 µA (typ.) (@IOUT = 0 A) Low starting quiescent current Low-dropout voltage: VD = 0.5 V (max) (@IOUT = 0.5 A) Protection function: overheat/overcurrent Package type: PW-MOLD (TA48**F Series)
TO-220NIS (TA48**S Series) TA48**F Series has a lead bending type package which is a surface-mountable package and can be used for reflow soldering.
