CO is not required for stability; however it does improve transient response. For optimum stability and transient response locate CI CO as close as possible to the regulator. A common ground is required between the input and the output voltages. The input voltage must remain typically 2.0 V above the output voltage even during the low point on the input ripple voltage. 3, 4 1580µm (62.20 mils) 1860µm (73.23mils) (0,0) PAD FUNCTION COORDINATES (µm) X Y 1 V IN -400.5 526.5 2 GND 730.5 567 3 V OUT -345.5 -657.5 4 V OUT -554.5 -541.5 CONNECT CHIP BACK TO GND 1 2 DIE ID
