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
