Function
Enable (LP38502 only). Pull high to enable the output, low to disable the output. This pin has
no internal bias and must be either tied to the input voltage, or actively driven.
In the LP38500, this pin has no internal connections. It can be left floating or used for trace
routing.

The DAP is used to remove heat from the device by conducting it to the copper clad area on
the PCB which acts as the heatsink. The DAP is electrically connected to the backside of the
die. The DAP must be connected to ground potential, but can not be used as the only ground
connection.
