For additional information on this topic please refer to the TEA1733(L) application note. R23/R24 The resistor dividers R23 and R24 determine the output voltage. V o = 2.5 V R23 + R24 R24 C13/C14 The voltage rating of these electrolytic capacitors must be chosen higher than the output voltage. For lower output currents the capacity value can be decreased.
