Page 11 TK715xxAS APPLICATION INFORMATION (CONT) INPUT-OUTPUT CAPACITORS (CONT) OUTPUT NOISE IMPROVEMENT An RC filter can be added to the output stage of the regulator to reduce output noise when the input voltage is high and the output current only makes small changes. Select a regulator with a slightly higher output voltage because the final output voltage will be reduced by the RC filter. If the output current does make a large change, the output voltage will change. The following table shows output noise, and output voltage for various values of R OUT and COUT using a 3.5 V device. V IN = 4.0 V, CIN = 10 mF (aluminum electrolytic), COUT = (see table), ROUT = (see table) RIPPLE REJECTION RATIO An RC filter can be added to the input stage of the regulator to increase the ripple rejection when the input voltage is high. Even if the resulting difference between V IN at the regulator (after the RC filter) and VOUT is small the TK71533AS will output a stable voltage. The voltage dropped across the RC filter depends on the value of the input ripple noise. Select the value of R IN such that the lowest value of VIN plus the ripple noise after the RC filter (peak to peak) is the output voltage plus 0.2 V.
