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 1900µm (74.80 mils) 1400µm (55.11 mils) (0,0) 4 1 COORDINATES (µm) PAD FUNCTION X Y
