TA48015F
TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic
TA48015F
1.5 V Three-Terminal Low Dropout Voltage Regulator with Output Current of 1 A
The TA48015F consists of fixed-positive-output, low-dropout regulators with an output current of 1 A (max) that utilize V-PNP transistors for the output stage. This product responds to the need for low-voltage and low-power dissipation devices for use in consumer electronics and industrial appliances.

Thermal resistance
Note 1: External current and voltage ((including negative voltage) should not be applied to pins not specified. Note 2: 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).

Electrical Characteristics for All Products
Generally, the characteristics of power supply ICs change according to temperature fluctuations. The specification Tj = 25 is based on a state where temperature increase has no effect (assuming no fluctuation in the characteristics) as ascertained by pulse tests.

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 so that there is no problem even in high or low temperatures.
