TA48S018,02,025,03,033,05F TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic TA48S018F, TA48S02F, TA48S025F, TA48S03F, TA48S033F, TA48S05F 1-A Output Current and Low Dropout Voltage Regulator with ON/OFF Control Switch The TA48S**F series consists of small-surface mount type low-dropout regulators with an output current of 1 A (maximum) and an ON/OFF control switch. Control by an EN (ON/OFF) terminal enables the regulator to be operated only when required (output ON). Therefore these newly developed regulators are suitable for use in the power supply circuits of AV, OA and other digital devices equipped with a stand-by function, and of battery-operated portable data devices of various types, where they will contribute to energy saving. Moreover, the regulators have an output voltage line-up starting from 1.8V, and which corresponds to the under-voltage of various devices. Weight: 0.29 g (typ.)
