| 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.) Features Built-in ON/OFF control function (active high) Maximum output current: 1 A Low output voltage: 1.8/2.0/2.5/3.0/3.3/5.0 V Output voltage accuracy: VOUT 3% (@Tj = 25C) Low standby current: 800 A (typ.) (@IOUT = 0 A) Low quiescent current (output OFF mode): 0.5A (typ.) Low-dropout voltage: 0.5 V (max) (@IOUT = 0.5 A) Protection function: Over current/over temperature/ASO Package type: Surface-mount 5-pin PW-MOLD Pin Assignment 3 48S**F Part No. (or abbreviation code) Lot No. (weekly code) 12345 1: INPUT(IN) 2: ENABLE (EN) 3: GND 4: NC 5: OUTPUT (OUT) A line indicates lead (Pb)-free package or lead (Pb)-free finish.

Note 3: Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum ratings and the operating ranges. Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook ("Handling Precautions"/Derating Concept and Methods) and individual reliability data (i.e. reliability test report and estimated failure rate, etc).
