... Series Resistance) value with leads kept as short as possible. Capacitors with long leads increase ripple voltage due to lead inductance. Like all Low-Dropout Regulators, the RE46C109 requires an output capacitor connected between VREG (output) and VSS to stabilize the internal control loop. The recommended capacitance is 10uF. Capacitor values larger than 10uF are acceptable ...
