APPLICATION INFORMATION
Optional low noise feature. A small value capacitor connected between
BYPASS and GROUND lowers output noise voltage level (100pF -
10nF).
DO NOT CONNECT. This pin is used for post package test and should
be left floating.
Device ground.
Input source voltage.
Regulated output voltage.
Remote sense. Tie directly to output or remotely at point of load for best
regulation.
No internal connection.
Enabled above turn-on threshold voltage. Pull to ground to disable.
The exposed die attach pad should be connected to a thermal pad at
ground potential. For additional information on using National
Semiconductor’s No Pull Back LLP package, please refer to LLP
application note AN-1187.
