technical data january, 2011, rev. 0 1 5- v low - drop voltage regulator ile 4260 is a 5 - v low - drop fixed - voltage regulator in p - to220 - 5 package. the maximum input voltage is 42 v (65 v 400 ms). the device can produce an output current of more than 500 ma. it is shortcircuit - proof and incorporates temperature protection that disables the circuit at unpermissibly high temperatures. due to the wide temperature range of ? 40 to 150 c, the ile 4260 is also suitable for use in automotive applications. the ic regulates an input voltage v i in the range 6 < v i < 35 v to v q nominal =5.0 v. a reset signal is generated for an output voltage of v q < 4.75 v. the reset delay can be set externally with a capacitor. if the output current is reduced below 10 ma, the regulator switches internally t o standby and the reset generator is turned off. the standby current drops to max. 700 a. features ? low - drop voltage ? very low quiescent current ? low starting current consumption ? integrated temperature protection ? protection against reverse po larity ? input voltage up to 42 v ? overvoltage protection up to 65 v ( 400 ms) ? short - circuit proof ? suited for automotive electronics ? wide temperature range il e42 60- 2 ile4260s - 2 ile4260 - 2 i l e 42 60s - 2 p - t o220 - 5 - 2 i l e 42 60 - 2 p - t o220 - 5 - 1 t a = - 40 125 c for all packages

ile42 6 0 -2 january, 2011, rev. 0 1 ci rcuit description the control amplifier compares a reference voltage, which is kept highly accurate by resistance adjustment, to a voltage that is proportional to the output voltage and drives the base of the series transistor via a buffer. saturation con trol as a function of the load current prevents any over - saturation of the power element. if the output voltage goes below 96% of its typical value, an external capacitor is discharged on pin 4 by the reset generator. if the voltage on the capacitor reache s the lower threshold v st , a reset signal is issued on pin 2 and not cancelled again until the upper threshold v dt is exceeded. for an output current of less than i qn off = 10 ma the standby changeover turns off the reset generator. the latter is turned on again when the output current increases, the output voltage drops below 4.2 v or the delay capacitor is discharged by external measures. the ic also incorporates a number of internal circuits for protection against: ? overload ? overvoltage ? overtemper ature ? reverse polarity block d iagram
