Parameter Rating VIN to GND −0.3 V to +6.5 V VOUT to GND −0.3 V to VIN EN to GND −0.3 V to +6.5 V Storage Temperature Range −65°C to +150°C Operating Junction Temperature Range −40°C to +125°C Soldering Conditions JEDEC J-STD-020 Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only; functional operation of the device at these or any other conditions above those indicated in the operational section of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. THERMAL DATA Absolute maximum ratings apply individually only, not in combination. The ADP121 can be damaged when the junction temperature limits are exceeded. Monitoring the ambient temperature does not guarantee that the junction temperature (TJ) is within the specified temperature limits. In applications with high power dissipation and poor thermal resistance, the maximum ambient temperature may have to be derated. In applications with moderate power dissipation and low PCB thermal resistance, the maximum ambient temperature can exceed the maximum limit as long as the junction temperature is within specification limits. TJ of the device is dependent on the ambient temperature (TA), the power dissipation of the device (PD), and the junction-to-ambient thermal resistance of the package (θJA). TJ is calculated from TA and PD using the following formula: TJ = TA + (PD × θJA) Junction-to-ambient thermal resistance, θJA, is based on modeling and calculation using a four-layer board. The junction-to-ambient thermal resistance is highly dependent on the application and board layout. In applications where high maximum power dissipation exists, close attention to thermal board design is required. The value of θJA may vary, depending on PCB material, layout, and environmental conditions. The specified values of θJA are based on a 4-layer, 4” × 3”, circuit board. Refer to JESD 51-7 and JESD 51-9 for detailed information on the board construction. For additional information, see AN-617 Application Note, MicroCSPTM Wafer Level Chip Scale Package. ΨJB is the junction-to-board thermal characterization parameter measured in °C/W. ΨJB is based on modeling and calculation using a four-layer board. The JESD51-12 Guidelines for Reporting and Using Package Thermal Information states that thermal characterization parameters are not the same as thermal resistances. ΨJB measures the component power flowing through multiple thermal paths rather than a single path as in thermal resistance, θJB. Therefore, ΨJB thermal paths include convection from the top of the package as well as radiation from the package, factors that make ΨJB more useful in real- world applications. Maximum TJ is calculated from the board temperature (TB) and PD using the following formula: TJ = TB + (PD × ΨJB) Refer to JESD51-8 and JESD51-12 for more detailed information about ΨJB. THERMAL RESISTANCE θJA and ΨJB are specified for the worst-case conditions, that is, a device soldered in a circuit board for surface-mount packages. Table 4.
