COMPENSATION-CAPACITOR SELECTION INFORMATION
The TL2217-285 is a low-dropout regulator. This means that the capacitance loading is important to the performance
of the regulator because it is a vital part of the control loop. The capacitor value and the equivalent series resistance
(ESR) both affect the control loop and must be defined for the load range and the temperature range. Figure 3 and
Figure 4 can be used to establish the capacitance value and ESR range for best regulator performance.
