1A Output Current and Low Dropout Voltage Regulator with ON/OFF Control Switch

The TA48S***AF 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 1.5V, corresponding to the lower voltage of various

devices.
