Table 1: Absolute Maximum Ratings
(*) Our SO-8 package used for Voltage Regulators is modified internally to have pins 2, 3, 6 and 7 electrically communed to the die attach
flag. This particular frame decreases the total thermal resistance of the package and increases its ability to dissipate power when an appro-
priate area of copper on the printed circuit board is available for heatsinking. The external dimensions are the same as for the standard SO-8.

Figure 1: Test Circuits
Note: If the Inhibit pin is left floating, the regulator is in ON mode. However, to avoid any noise picking-up, it is suggested to ground it when
the Inhibit function is not used.

| LE27CZAP | Acoustically monitors the flow of a liquid in a pip to verify upstream components are functioning correctly. Particularly suitable for areas around turbid flow (around valves, joints, elbows, etc.). |
| LE47CZAP | Monitors a steady state temperature and provides an alarm if the desired temperature measurement rises about the set point. |
| LE27CZTR | Monitors a steady state vibration and provides an alarm if the desired vibration measurement rises above the set point. |
