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.

Note 2: Do not apply current and voltage (including reverse polarity) to any pin that is not specified. 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).

Precaution on Application
Tj = 25°C in the measurement conditions of each item is a regulation for where a pulse test is carried out and any drift in the electrical characteristic due to a rise in the junction temperature of the chip may be disregarded. Depending on the load conditions, a steep increase in the input voltage applied (VIN) may cause a momentary rise in output voltage (VOUT) even if the EN (enable) pin is Low. Treat with care.
Standard Application Circuit
TA48S**F CIN 0.33 μF CPU etc. IN EN OUT NC COUT 47 μF LOAD
GND
Be sure to connect a capacitor near the input terminal and output terminal between both terminals and GND. The capacitances should be determined experimentally. In particular, adequate investigation should be made to ensure there are no problems even in high or low temperatures.
