tle 7274 data sheet 7 rev. 1.1, 2005-07-30 application information figure 3 application diagram input, output an input capacitor is necessary for damping line influences. a resistor of approx. 1 ? in series with c i , can damp the lc of the input inductivity and the input capacitor. in contrast to most low drop voltage regulators the tle 7274 only needs moderate capacitance at the output to assure stability of the regulation loop. this offers more design flexibility to the circuit designer providing for cost efficient solutions. the tle 7274 requires a ceramic output capacitor of at least 470 nf. in order to damp influences resulting from load current surges it is recommended to add an additional electrolytic capacitor of 4.7 f to 47 f at the output as shown in figure 3 . tle 7274 q i gnd 2, tab aea03614.vsd bandgap reference charge pump overtemperature shutdown 1 1 100 nf v bat 3 470 nf v cc 4.7 f +
data sheet 8 rev. 1.1, 2005-07-30 tle 7274 additionally a buffer capacitor c b of > 10 f should be used for the output to suppress influences from load surges to the voltage levels. this one can either be an aluminum electrolytic capacitor or a tantalum capac itor following the application requirements. a general recommendation is to keep the drop over the equivalent serial resistor (esr) together with the discharge of the blocking capacitor below the allowed headroom of the application to be supplied (e.g. typ. dv q = 350mv). since the regulator output current roughly rises linearly with time the discharge of the capacitor can be calculated as follows: dvc b = di q *dt/c b the drop across the esr calculates as: dv esr = di*esr to prevent a reset the following relationship must be fullfilled: dv c + dv esr < v rh = 350mv example: assuming a load current change of c b = 100ma, a blocking capacitor of di q = 22f and a typical regulator reaction time under normal operating conditions of dt ~ 25s and for special dynamic load conditions, such as load step from very low base load, a reaction time of dt ~ 75s.. dv c = di q *dt/c b = 100ma * 25s/22f = 113mv so for the esr we can allow dv esr = v rh2 - dv c = 350mv - 113mv = 236mv the permissible esr becomes: esr = dv esr / di q = 236mv/100ma = 2.36ohm during design-in of the tle7469 product family, special care needs to be taken with regards to the regulators reaction time to sudden load current changes starting from very low pre-load as well as cyclic load changes. the application note ? tle7x voltage regulators - application note about transient response at ultra low quiescent current voltage regulators ? (see 3_cip05405.pdf) gives important hints for successful design-in of the voltage regulators of the tle7x family.
