Toshiba's TA48 series consists of fixed-positive-output, low-dropout regulators with an output current of 1A (maximum) that utilize V-PNP transistors for the output stage. In response to the need for low-voltage and low-power dissipation devices for use in consumer electronics and industrial appliances, the series offers devices with the following low output voltages: 1.5V, 1.8V, 2.5V, 3.3V, 5V, 8V, and 9V.
The TA48S series consists of small-surface mount type low-dropout regulators with an output current of 1A (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). These regulators are suitable for use in the power supply circuits of AV, OA, and other digital devices equipped with a stand-by function. They are also suitable for battery-operated portable data devices of various types where they will contribute to energy savings. Moreover, the regulators have an output voltage line-up starting from 1.5V, corresponding to the lower voltage of various devices.
