Function
Enable (LP38501 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 LP38503, this pin has no internal connections. It can be left floating or used for trace
routing.

The DAP is used as a thermal connection to remove heat from the device to the circuit board
copper clad area 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.
