Absolute Maximum Rating is limits beyond which damage to the device may occur. For guaranteed specifications and test conditions see the Electrical Characteristics. 2. The device is not guaranteed to operate outside its operating rating. 3. Devices are ESD sensitive. Handling precautions recommended. 4. The maximum allowable power dissipation is a function of the maximum junction temperature, T J, the junction to ambient thermal resistance, RӨJA, and the ambient temperature, T A. Exceeding the maximum allowable power dissipation will cause excessive die temperature, and the regulator will go into thermal shutdown. The effective value of RӨJA can be reduced by using a heat sink, PD(max) = (TJ(max) – TA) / RӨJA 5. Dropout voltage is defined as the input to output differential at which the output voltage drops -1% below its nominal value measured at 1V differential. 6. Ground pin current is the regulator quiescent current. The total current drawn from the source is the sum of the ground pin current and output load current, IGND = IIN - IOUT for fix output voltage, , IGND = IIN - IOUT +10mA for fix reference output voltage in full load regulation. 7.

APPLICATION INFORMATION The TS39104 is a high performance with low dropout voltage regulator suitable for moderate to high current and voltage regulator application. Its 630mV dropout voltage at full load and over temperature makes it especially tR valuable in battery power systems and as high efficiency noise filters in post regulator applications. Unlike normal NPN transistor design, where the base to emitter voltage drop and collector to emitter saturation voltage limit the minimum dropout voltage, dropout performance of the PNP output of these devices is limited only by low V CE saturation voltage. No The TS39104 s fully protected from damage due to fault conditions. Linear current limiting is provided. Output current during overload conditions is constant. Thermal shutdown the device when the die temperature exceeds the maximum safe operating temperature. Transient protection allows device survival even when the input voltage spikes above and below nominal. The output structure of these regulators allows voltages in excess of the desired output voltage to be applied without reverse current flow Input Capacitor Requirement An input capacitor of 1µF or greater is recommended when the device is more than 4” away from the bulk AC supply capacitance or when the supply is a battery. Small, surface mount, ceramic chip capacitors can be used for bypassing. Larger values will help to improve ripple rejection by bypassing the input to the regulator, further improving the integrity of the output voltage. Minimum Load Current The TS39104 is specified between finite loads. If the output current is too small leakage currents dominate and the output voltage rises. A 10mA minimum load current is necessary for proper regulation. 4 Version: D1706 TS39104CS Taiwan Semiconductor APPLICATION INFORMATION (Continue) Output Capacitor Requirement The TS39104 requires an output capacitor to maintain stability and improve transient response is necessary. The value of this capacitor is dependent upon the output current, lower currents allow smaller capacitors. TS39104 output capacitor selection is dependent upon the ESR of the output capacitor to maintain stability. When the output capacitor is 10µF or greater, the output capacitor should have an ESR less than 2Ω. This will improve transient response as well as promote stability. Ultra low ESR capacitors (
