tle4296-2 application information data sheet 9 rev. 1.11, 2011-02-10 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 in the tle4296-2 the output voltage is divided and compared to an internal reference of 2.5 v typical. the regulation loop controls the output to achieve a stabilized output voltage. figure 3 shows a typical application circui t. in order to maintain the stabilit y of the control loop the tle4296-2 output requires an output capacitor c q of at least 3.3 f with a maximum permissible esr of 2 ? . it is recommended to use a multi layer ceramic capacitor for c q , e.g. the tdk c3216x7r1c475m with a nominal capacitance of 4.7 f. aluminum electrolytic as well as tantalum capacitors do not cover the required esr range over the full operating temperature range of t j = -40 c to +150 c. at the input of the regulator an input capacitor is ne cessary for compensa ting line influences (100 nf ceramic capacitor recommended). a resistor of approx. 1 ? in series with c i , can damp any oscillati on occurring due the input inductivity and th e input capacitor. if the regulator is source d via long input lines of several meters it is recommended to place an additi onal electrolytic capacitor 47 f at the input. tle 4296-2g c aes02313_4296-2 c q 100 nf 1 inhibit 3 4 2,5 4.7 f 3.0v / 3.3v / 5.0v gnd inh v q + 0.5v to 45v ,nom q e.g. tdk c3216x7r1c475m
