Pin Descriptions Pin Pn in Name Pin Functio Number 1J AD This pin is the negative side of the reference voltage for the device. Transient response can be improved by adding a small bypass capacitor from the adjust pin to ground. GND This pin is the bottom end of the internal resistor feedback chain for fixed output voltage parts, and should be connected to ground. 2T OU This is the power output of the device, and is electrically connected to the TAB. 3NI.
