Application Notes continued:
(See application circuit)
Capacitor Selection:
To achieve minimum output voltage ripple, the output capacitor C
(for VPOS) should have a low ESR (Effective
4
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.
PCB Layout Suggestions:
Due to large transient currents flow in the V
, V
and V
terminals, minimizing both input and output ripple is

accomplished by placing capacitors as close as possible to the regulator using short direct circuit wiring or traces.
