The SP6213 features low dropout voltage (250mV at 100mA ), low ground current (135µA at full load) and low, 65µA quiescent current. Designed specifically for hand-held, battery powered devices, the device includes an enable/shutdown pin. Regulator ground current increases only slightly in dropout to extend battery life. The SP6213 is offered in an industry standard 5-pin SC-70 package. SP6213 is available in 1.8V, 2.5V, 2.7V, 2.85V, 3.0V, 3.3V and 5.0V fixed output voltages.

Exceeding the absolute maximum rating may damage the device. Note 2. The device is not guaranteed to function outside its operating rating. Note 3. The maximum allowable power dissipation at any TA (ambient temperature) is PD (MAX) = (TJ (MAX)– TA) / qJA. Exceeding the maximum allowable power dissipation will result in excessive die temperature, and the regulator will go into thermal shutdown. The QJA of the SP6213 (SC-70-5) is 330°C/W mounted on a PC board with minimum copper area (see “Thermal Considerations” section for further details). Note 4. Output voltage temperature coefficient is defined as the worst case voltage change divided by the total temperature range. Note 5. Load Regulation is measured at constant junction temperature using low duty cycle pulse testing. Parts are tested for load regulation in the load range. Changes in output voltage due to heating effects are covered by the thermal regulation specification. Note 6. Dropout Voltage is defined as the input to output differential at which the output voltage drops 2% below its nominal value measured at 0.5V differential. Not applicable to output voltages less than 2.7V. Note 7. Ground pin current is the regulator quiescent current. The total current drawn from the supply is the sum of the load current plus the ground pin current. Note 8. Thermal regulation is defined as the change in output voltage at a time ”t” after a change inpower dissipation is applied, excluding load or line regulation effects. Specifications are for a 100mA load pulse at VIN = 6V for t = 10ms. Note 9. Devices are ESD sensitive. Handling precautions are recommended.

To determine the maximum power dissipation of the package, use the junction-to-ambient thermal resistance of the device and the following basic equation: PD = (TJ(max) - TA) / ΘJA Enable/Shutdown Operation The SP6213 is turned off by pulling the EN pin low and turned on by pulling it high. If this enable/ shutdown feature is not required, EN should be tied to VIN to keep the regulator output on at all times. Input Capacitor A small capacitor of about 1µF is required from VIN to GND if e.g. a battery is used as the input. Any good quality ceramic or tantalum capacitor may be used at the input. TJ(max) is the maximum junction temperature of the die and is 125°C. TA is the ambient operating. ΘJA is the junction-to-ambient thermal resistance for the regulator and is layout dependent.The actual power dissipation of the regulator circuit can be determined using one simple equation: PD = (VIN - VOUT)*IOUT + VIN*IGND Output Capacitor An output capacitor is required between VOUT and GND to prevent oscillation. The minimum size of the output capacitor is a 0.47 µF ceramic. The given datasheet values relate to an IC with a ceramic output capacitor of 1µF. Larger values make the IC more stable which means an improvement of the regulator’s transient response. For a lower output current, the output capacitance can be chosen smaller in order to have the same output stability. 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, if we are operating the SP6213 at 3.0V output at room temperature, with a minimum footprint layout, we can determine the maximum input voltage for a set output current. PD(max) =[(125°C -25°C) / (330°C/W)] = 303 mW. No Load Stability The SP6213 will remain stable and in regulation with no external load (other than the internal voltage driver) unlike many other voltage regulators. This is especially important in CMOS RAM keep-alive applications. To prevent the device from entering thermal shutdown, maximum power dissipation can not be exceeded. Using the output voltage of 3.0V and an output current of 100 mA, the maximum input voltage can be determined. Ground pin current can be taken from the electrical spec’s- table (0.135 mA at 100 mA). The maximum input voltage is determined as follows: 303mW = (VIN – 3.0V)*100mA + VIN*0.135mA Thermal Considerations The SP6213 is designed to provide 100 mA of continuous current in a very tiny package. Maximum power dissipation can be calculated based on Rev. 9/22/03 After calculations, we find that the maximum input voltage of a 3.0V application at 100mA of output current in an SC-70-5 package is 6.02V.
