However, the output current is limited by the restriction of power dissipation which differs from packages. A heat sink may be required depending on the maximum power dissipation and maximum ambient temperature of application. With respect to the applied package, the maximum output current of 1.5A may be still undeliverable. * See Application Information Oct R /9 HTC

Stresses listed as the absolute maximum ratings may cause permanent damage to the device. These are for stress ratings. Functional operating of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may remain possibly to affect device reliability. Note 2. The minimum operating value for input voltage is equal to either (V OUT,NOM V DROP) or 2.5V, whichever is greater. Note 3. Output voltage line regulation is defined as the change in output voltage from the nominal value due to change in the input line voltage. Output voltage load regulation is defined as the change in output voltage from the nominal value due to change in load current. Note 4. Regulation is measured at constant junction temperature by using a 20ms current pulse. Devices are tested for load regulation in the load range from 10mA to 1.5A Note 5. Dropout voltage is defined as the minimum input to output differential voltage at which the output drops 2% below the nominal value. Dropout voltage specification applies only to output voltages of 2.5V and above. For output voltages below 2.5V, the dropout voltage is nothing but the input to output differential, since the minimum input voltage is 2.5V Note 6. Ground current, or quiescent current, is the difference between input and output currents. It's defined by I 1 = I IN I OUT under the given loading condition. The total current drawn from the supply is the sum of the load current plus the ground pin current. Note 7. Ground current, or standby current, is the input current drawn by a regulator when the output voltage is disabled by an enable signal. Oct R /9 HTC

8 APPLICATION INFORMATION Output Adjustment (Adjustable Version) An adjustable output device has output voltage range of 1.145V to 5.0V. To obtain a desired output voltage, the following equation can be used with R1 resistor range of 10kΩ to 220kΩ V = R OUT To enhance output stability, a capacitor of 68pF to 100pF can be placed in series with V OUT and ADJ. SSE Pin In applications where the regulator output is not very close to the load, the TJ3965 can provide better remote load regulation characteristics using the SSE pin. TJ3965 regulates the voltage at the output pin. Hence, the voltage at the remote load will be lower than the voltage at the output pin as a value of the voltage drop across the trace series resistance. If the sense option pin is not required, the sense pin must be connected to the V OUT pin. Connecting the sense pin to the remote load will provide regulation at the remote load because the TJ3965 regulates the voltage at the sense pin when the sense option pin is used. R Maximum Output Current Capability The TJ3965 can deliver a continuous current of 1.5A over the full operating junction temperature range. However, the output current is limited by the restriction of power dissipation which differs from packages. A heat sink may be required depending on the maximum power dissipation and maximum ambient temperature of application. With respect to the applied package, the maximum output current of 1.5A may be still undeliverable due to the restriction of the power dissipation of TJ3965. Under all possible conditions, the junction temperature must be within the range specified under operating conditions. The temperatures over the device are given by: T C = T A P D X θ CA T J = T C P D X θ JC T J = T A P D X θ JA where T J is the junction temperature, T C is the case temperature, T A is the ambient temperature, P D is the total power dissipation of the device, θ CA is the thermal resistance of casetoambient, θ JC is the thermal Oct R /9 HTC
9 resistance of junctiontocase, and θ JA is the thermal resistance of junction to ambient. The total power dissipation of the device is given by: P D = P IN P OUT = (V IN X I IN ) (V OUT X I OUT ) = (V IN X (I OUT I )) (V OUT X I OUT ) = (V IN V OUT ) X I OUT V IN X I where I is the operating ground current of the device which is specified at the Electrical Characteristics. The maximum allowable temperature rise (T Rmax ) depends on the maximum ambient temperature (T Amax ) of the application, and the maximum allowable junction temperature (T Jmax ): T Rmax = T Jmax T Amax The maximum allowable value for junctiontoambient thermal resistance, θ JA, can be calculated using the formula: θ JA = T Rmax / P D TJ3965 is available in SOT223, MSOP8, SOP8PP, TO263, and TO220 packages. The thermal resistance depends on amount of copper area or heat sink, and on air flow. If the maximum allowable value of θ JA calculated above is over 140 C/W for SO223 package, over 220 C/W for MSOP8 package, over 165 C/W for SOP8 package, over 170 C/W for SOP8PP package, over 80 C/W for TO263 package, over 75 C/W for TO220 package, no heat sink is needed since the package can dissipate enough heat to satisfy these requirements. If the value for allowable θ JA falls near or below these limits, a heat sink or proper area of copper plane is required. In summary, the absolute maximum ratings of thermal resistances are as follow: Absolute Maximum Ratings of Thermal Resistance No heat sink / No air flow / No adjacent heat source / T A = 25 C Characteristic Symbol Max.
