Pin Descriptions Pe in Pn in Nam Pin Functio 1T ADJUS This pin is the negative side of the reference voltage for adjustable devices. Transient response can be improved by adding a small bypass capacitor from the adjust pin to ground. GROUND This pin is the bottom end of the internal resistor feedback chain for fixed output voltage parts, and should be connected to ground. 2T OUTPU This is the power output of the device and is electrically connected to the TAB. 3T INPU This is the input supply pin for both the control circuitry and the pass device.
