1 A 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 1.5 V, corresponding to the lower voltage of various
devices.

The product(s) in this document (“Product”) contain functions intended to protect the Product from
temporary small overloads such as minor short-term overcurrent or overheating. The protective
functions do not necessarily protect Product under all circumstances. When incorporating Product into
your system, please design the system (1) to avoid such overloads upon the Product, and (2) to shut
down or otherwise relieve the Product of such overload conditions immediately upon occurrence. For
details, please refer to the notes appearing below in this document and other documents referenced in
this document.
