Figure 2. Standard Application
A common ground is required between the input and the output voltages. The input voltage must remain typically 2.0 V above the output
voltage even during the low point on the input ripple voltage.

Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the
Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect
device reliability.

2. Thermal Resistance, Junction−to−Ambient depends on P.C.B. Copper area. See details in Figure 8.
Thermal Resistance, Junction−to−Case is not defined. SOIC 8 lead and TO-92 packages that do not have a heat sink like other packages
may have. This is the reason that a Theta JC is never specified. A little heat transfer will occur through the package but since it is plastic, it is
minimal. The majority of the heat that is transferred is through the leads where they connect to the circuit board.
