The TL760M 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. Figure 1 can be used to
establish the capacitance value and ESR range for the best regulator performance.
