The use of an NMOS pass transistor offers several
advantages in applications. Unlike PMOS topology devices,
the output capacitor has reduced impact on loop stability.
Vin to Vout operating voltage difference can be very low
compared with standard PMOS regulators in very low Vin
applications.

Enable Operation
Thermal Protection
The enable pin will turn the regulator on or off. The
threshold limits are covered in the electrical characteristics
table in this data sheet. If the enable function is not to be used
Internal thermal shutdown (TSD) circuitry is provided to
protect the integrated circuit in the event that the maximum
junction temperature is exceeded. When TSD activated , the
regulator output turns off. When cooling down under the low
temperature threshold, device output is activated again. This
TSD feature is provided to prevent failures from accidental
overheating.
Activation of the thermal protection circuit indicates
excessive power dissipation or inadequate heatsinking. For
reliable operation, junction temperature should be limited to
+85°C maximum.

Current Limitation
The internal Current Limitation circuitry allows the
device to supply the full 1 A nominal current and short time
current peaks up to 1.3 A but protects the device against
