tle42764 application information data sheet 12 rev. 1.1, 2009-10-09 6 application information note: the following information is given as a hint for the implementation of the device only and shall not be regarded as a description or warranty of a certain functionality, condition or quality of the device. figure 3 application diagram a typical application circuit of the tle42764 is shown in figure 3 . it shows a generic configuration of the voltage regulator, with the recommendable minimu m number of components one should use. theoretically, if there is no risk of high frequency noise at all, even the small input f ilter capacitor can be omitted. for a normal operation mode of the device the only required device is the out put capacitor, for the tle42764gv and the tle42764dv additionally the resistor divider. howe ver, depending on the application?s en vironment, additional components like an input buffer capacitor or a reverse polarity protection diode can be considered as well. input filter capacitor a small ceramic capacitor (e.g. 100nf in figure 3 ) at the device?s input helps filtering high frequency noise. to reach the best filter effect, this capacitor should be placed as close as possible to the device?s input pin. the input filter capacitor does not have an influence on the stability of the device?s regulation loop. output capacitor c q the output capacitor is the only external component that is required in any case as it is a part of the device?s regulating loop. to maintain stability of this loop, the tl e42764 requires an output ca pacitor respecting the values given in ?functional range? on page 5 . adjusting the output voltage of variable output regulators tle42764gv, tle42764dv the output voltage of the tle42764g v and the tle42764dv can be adjus ted between 2.5 v and 20 v by an external resistor divider, connect ed to the voltage adjust pin va. the pin va is connected to the error amplifier comparing th e voltage at this pin with the internal reference voltage of typically 2.5 v. aes02046 c q r 1 2 r output input tle42764 optional for adjustable voltage regulator i c voltage adjust e.g. kl 15 ) * ) * ) * * ) i 1q 5 gnd va 4 3 2 en
