Input Bypass Capacitor An input capacitor is recommended.A 10uF tantalum on the input is a suitable input bypassing for almost all applications. 2. Output Capacitor The output capacitor is critical in maintaining regulator stability,and must meet the required conditions for both minimum amount of capacitance and ESR (Equivalent Series Resistance).The minimum output capacitance required by the ME6117 is 10µF,if a tantalum capacitor is used.Any increase of the output capacitance will merely improve the loop stability and transient response.The ESR of the output capacitor should be less than 0.5Ω . 3. Load Regulation The ME6117 regulates the voltage that appears between its output and ground pins,or between its output and adjust pins. In some cases, line resistances can introduce errors to the voltage across the load. To obtain the best load regulation, a few precautions are needed. Figure1, shows a typical application using a fixed output regulator.The Rt1 and Rt2 are the line resistances.It is obvious that the VLOAD is less than the VOUT by the sum of the voltage drops along the line resistances. In this case, the load regulation seen at the RLOAD would be degraded from the datasheet specification. To improve this , the load should be tied directly to the output terminal on the positive side and directly tied to the ground terminal on the negative side. FIGURE 1.
