Exceeding the absolute maximum rating may damage the device. 2. The maximum allowable power dissipation at any Ta is Pd(max) = [T J(MAX) - Ta] + ӨJA . Exceeding the maximum allowable power dissipation will result in excessive die temperature, and the regulator will go into thermal shutdown. 3. The device is not guaranteed to function outside its operating rating. 4: Output voltage temperature coefficient is defined as the worst case voltage change divided by the total temperature range. 5: Regulation is measured at constant junction temperature using low duty cycle pulse testing. Parts are tested for load regulation in the load range from 1mA to 80mA. Changes in output voltage due to heating effects are covered by the thermal regulation specification. 6: Dropout voltage is defined as the input to output differential at which the output voltage drops 2% below its nominal value measured at 1V differential. 7: Ground pin current is the regulator quiescent current plus pass transistor base current. The total current drawn from the supply is the sum of the load current plus the ground pin current. 8: Thermal regulation is defined as the change in output voltage at a time “t” after a change in power dissipation is applied, excluding load or line regulation effects. Specifications are for a 80mA load pulse at V IN =16V for t=10mS.

Application Information

TS5204 series is designed to provide 80mA of continuous current in a very small package. Maximum power dissipation can be calculated based on the output current and the voltage drop across the part. To determine the maximum power dissipation of the package, use the junction-ambient thermal resistance of the device and the following basic equation: PD(MAX) = [ T J(MAX) – TA ] / ΘJA Tj(max) is the maximum junction temperature of the die(125 oC), and Ta is the ambient operating temperature. ΘJA is layout dependent, the actual power dissipation of the regulator circuit can be determined using the equation: PD = (V IN – VOUT ) * I OUT + V IN * I GND Substituting Pd(max) for Pd and solving for the operating conditions that are critical to the application will give the maximum operating conditions for the regulator circuit. For example, when operating the TS5204CX33 at room temperature with a minimum footprint layout, the maximum input voltage for a set output current can be determined as follows: PD(MAX) = (125 oC – 25 oC) / 220 oC/W The junction to ambient thermal resistance for the minimum footprint is 220 oC/W, the maximum power dissipation must not be exceeded for proper operation. Using the output voltage of 3.3V and an output current of 80mA, the maximum input voltage can be determined. From the electrical characteristics table, the maximum ground current for 80mA output current is 2.5mA. 445mW = (V IN – 3.3V ) * 120mA + V IN * 2.5mA 445mW = V IN * 120mA – 3.3 * 120mA + V IN * 2.5mA 445mW = V IN * 120mA – 395mW + V IN * 2.5mA 840mW = V IN * 122.5mA VIN (max) = 6.85V Therefore, a 3.3V application at 80mA of output current can accept a maximum input voltage of 6.85V in a SOT- 23 package. Input Capacitor Requirement An input capacitor of 0.1uF or greater is recommended when the device is more than 10” away from the bulk AC supply capacitance or when the supply is a battery. Output Capacitor Requirement The TS5204 series requires an output capacitor to maintain stability and improve transient response is necessary. 2.2uF minimum is recommended. Larger values improve the regulator’s transient response. The output capacitor value may be increased without limit. The output capacitor should have an ESR (effective series resistance) less than 5 Ω and a resonant frequency above 1MHz. Ultra low ESR capacitors can cause a low amplitude oscillation on the output and/or under damped transient response. Most of tantalum or aluminum electrolytic capacitors are adequate; film types will work. Since many aluminum electrolytic have electrolytes that freeze at about –30 oC, solid tantalums are recommended for operation below –25 oC. At lower values of output current, less output capacitance is required for output stability. The capacitor can be reduced to 0.47uF for current below 10mA or 0.33uF for currents below 1mA . No Load Stability The TS5204 series will remain stable and in regulation with no load, unlike many other voltage regulators. This is especially important in CMOS RAM keep alive applications. Dual Supply Operation When used in dual supply systems where the regulator load is returned to a negative supply, the output voltage must be diode clamped to ground.
