... TRACKING The ADP2119/ADP2120 have a tracking input, TRK, that allows the output voltage to track another voltage (master voltage). The tracking input is especially useful in core and I/O voltage tracking for FPGAs, DSPs, and ASICs. The internal error amplifier includes three positive inputs: the internal reference voltage, the soft start voltage, and the TRK voltage ...

... The load transient response depends on the inductor, the output capacitor, and the control loop. The ADP2119/ADP2120 have integrated loop compensation to provide a simple power solution design. Table 5 and Table 6 show the typical recommended inductors and capacitors for the ADP2119/ ADP2120. X5R or X7R ceramic capacitors are highly recommended. Table 5. Recommended L and C V ...

... Higher or lower inductor and output capacitor values can be used in the regulator, but the system stability and load transient performance need to be checked. The minimum output capacitor is 22 μF for the ADP2119 and 10 μF for the ADP2120, and the inductor range is 1 μH to 3.3 μH. Table 7. Recommended Inductors ...
