1.8 V, 2 V, 2.5 V, 3 V, 3.3 V, 5 V Three-Terminal Low Dropout Voltage Regulator with Output Current of 1 A
The TA48**F/S series 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. In response to the need for low-voltage and low-power dissipation devices which are used in consumer electronics and industrial appliances, the series offers devices with low output voltages: 1.8 V, 2 V, 2.5 V, 3 V, 3.3 V, 5 V.
(1) TA48**F
Features
Maximum output current: 1 A Output voltage accuracy: VOUT 3% (@Tj = 25C) Low standby current: 800 A (typ.) (@IOUT = 0 A) Low starting quiescent current Low-dropout voltage: VD = 0.5 V (max) (@IOUT = 0.5 A) Protection function: overheat/overcurrent Package type: PW-MOLD (TA48**F Series) TO-220NIS (TA48**S Series) TA48**F Series has a lead bending type package which is a surface-mountable package and can be used for reflow soldering.

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 temperature.
