TA48018,02,025,03,033,05F/S TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic TA48018F, TA4802F, TA48025F, TA4803F, TA48033F, TA4805F, TA48018S, TA4802S, TA48025S, TA4803S, TA48033S, TA4805S 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. (1) TA48**F 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.
