This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

Pin Descriptions for TO-263 THIN Package
Function
Enable. Pull high to enable the output, low to disable the output. This pin has no internal bias and
must be tied to the input voltage, or actively driven.

Regulated Output Voltage Pin
The feedback to the internal Error Amplifier to set the output voltage
The TO-263 THIN DAP connection is used as a thermal connection to remove heat from the device
to an external heat-sink in the form of the copper area on the printed circuit board. The DAP is
physically connected to backside of the die, but is not internally connected to device ground. The
DAP should be soldered to the Ground Plane copper..
