Thermal Resistance
Note 1: Absolute Maximum Ratings are limits beyond which damage to the device may occur. Operating Ratings are conditions under which operation of the
device is intended to be functional. For guaranteed specifications and test conditions, see the Electrical Characteristics.
Note 2: The human body model is a 100 pF capacitor discharged through a 1.5 kΩ resistor into each pin.
Note 3: For detailed information on soldering the plastic TSSOP package, refer to the Packaging Databook available from National Semiconductor.
Note 4: Minimum and Maximum limits are guaranteed through test, design, or statistical correlation using Statistical Quality Control (SQC) methods. Typical
values represent the most likely parametric norm at T
Outgoing Quality Level (AOQL).
Note 5: Device thermal limitations may limit usable range.
Note 6: The VCC regulator is intended for use solely as a bias supply for the LM5072, dropout assumes 3mA of external V
Note 7: During rear auxiliary operation, the RTN pin can be approximately -0.4V with respect to VEE. This is caused by normal internal bias currents, and will
not harm the device. Application of external voltage or current must not cause the absolute maximum rating to be exceeded.
