TA48LS00F TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic TA48LS00F 300 mA Output Current, Variable Output Voltage and Low Dropout Voltage Regulator with ON/OFF Control Switch The TA48LS00F consists of small-surface mount type low-dropout regulators with an output current of 300 mA (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). The output voltage can be arbitrarily set by external resistance. Therefore, the TA48LS00F can be used for a wide range of applications. TA48LS00F is 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 Weight : 0.017 g (Typ.) contribute to energy saving. Features Built-in ON/OFF control function (active high) Maximum output current : 300 mA Output voltage : V = 1.5 to 5.0 V OUT Reference voltage accuracy : V 2.3 % ( T = 25C) REF j Low quiescent current : 1 mA (Typ.) ( I = 0 A) OUT Low standby current (output OFF mode): 0.2 A (Typ.) Low-dropout voltage : 0.5 V (Max) ( V = 3.3 V, I = 150 m A) OUT OUT Protection function : Overcurrent / Thermal shutdown Package type : PS-8 Marking / Pin Assignment 8 7 6 5 Part No. Part No. (abbreviation code) 1 : N.C.
