tle 4270 data sheet version 1.3 3 2002-01-07 circuit 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 a series transistor via a buffer. saturation control as a function of the load current prevents any over-saturation of the power element. the ic also incorporates a number of internal circuits for protection against: overload overvoltage overtemperature reverse polarity application description the ic regulates an input voltage in the range of 5.5 v v i 36 v to v q,nom = 5.0 v. up to 26 v it produces a regulated output current of more than 650 ma. above 26 v the save-operating-area protection allows operation up to 36 v with a regulated output current of more than 300 ma. overvoltage protection limits operation at 42 v. the overvoltage protection hysteresis restores operation if the input voltage has dropped below 36 v. a reset signal is generated for an output voltage of v q 4.5 v. the delay for power-on reset can be set externally with a capacitor.

tle 4270 data sheet version 1.3 9 2002-01-07 design notes for external components an input capacitor c i is necessary for compensation of line influences. the resonant circuit consisting of lead inductance and input capacitance can be damped by a resistor of approx. 1 in series with c i . an output capacitor c q is necessary for the stability of the regulating circuit. stability is guaranteed at values of c q 22 f and an esr of 3 . reset circuitry if the output voltage decreases below 4.5 v, an external capacitor c d on pin 4 (d) will be discharged by the reset generator. if the voltage on this capacitor drops below v dl , a reset signal is generated on pin 2 (ro), i.e. reset output is set low. if the output voltage rises above the reset threshold, c d will be charged with constant current. after the power-on-reset time the voltage on the capacitor reaches v du and the reset output will be set high again. the value of the power-on-reset time can be set within a wide range depending of the capacitance of c d . reset timing the power-on reset delay time is defined by the charging time of an external capacitor c d which can be calculated as follows: c d =( t i d,c )/ v definitions: c d = delay capacitors t = reset delay time t rd i d,c = charge current, typical 14 ? v = v du , typical 1.8 v v du = upper reset timing threshold at c d for reset delay time t rd = v c d / i d,c the reset reaction time t rr is the time it takes the voltage regulator to set the reset out low after the output voltage has dropped below the reset threshold. it is typically 1 s for delay capacitor of 47 nf. for other values for c d the reaction time can be estimated using the following equation: t rr 20 s/f c d
