lm4040 improved precision micropower shunt voltage reference with multiple reverse breakdown voltages ______________________________________________________________________________________ 11 detailed description the lm4040 shunt references use the bandgap princi- ple to produce a stable, accurate voltage. the device behaves similarly to an ideal zener diode; a fixed volt- age is maintained across its output terminals when biased with 60? to 15ma of reverse current. the lm4040 behaves similarly to a silicon diode when biased with forward currents up 10ma. figure 3 shows a typical operating circuit. the lm4040 is ideal for providing a stable reference from a high- voltage power supply. applications information the lm4040? internal pass transistor is used to maintain a constant output voltage (v shunt ) by sinking the necessary amount of current across a source resistor. the source resistance (r s ) is determined from the load current (i load ) range, supply voltage (v s ) variations, v shunt , and desired quiescent current. choose the value of r s when v s is at a minimum and i load is at a maximum. maintain a minimum i shunt of 60? at all times. the r s value should be large enough to keep i shunt less than 15ma for proper regulation when v s is maximum and i load is at a minimum. to prevent damage to the device, i shunt should never exceed 20ma. therefore, the value of r s is bounded by the following equation: [v s(min) - v r ] / [60? + i load(max) ] > r s > [v s(max) - v r ] / [20ma + i load(min) ] choosing a larger resistance minimizes the total power dis- sipation in the circuit by reducing the shunt current (p d(total) = v s ? i shunt ). provide a safety margin to incorporate the worst-case tolerance of the resistor used. ensure that the resistor? power rating is adequate, using the following general power equation: pd r = i shunt ? (v s(max) - v shunt ) output capacitance the lm4040 does not require an external capacitor for fre- quency stability and is stable for any output capacitance. temperature performance the lm4040 typically exhibits an output voltage tem- perature coefficient within ?5ppm/?. the polarity of the temperature coefficient may be different from one device to another; some may have positive coefficients, and others may have negative coefficients. high temperature operation the maximum junction temperature of the lm4040 is +150?. the maximum operating temperature for the lm4040_e_ is +125?. at a maximum load current of 15ma and a maximum output voltage of 5v, the part will dissipate 75mw of power. the power dissipation limits of the 3-pin sc70 call for a derating value of 2.17mw/? above +70? and thus for 75mw of power dissipation, the part will self- heat to 35.56? above ambient temperature. if the ambient temperature is +125?, the part operates at 159.56?, thereby exceeding the maximum junction temperature value of +150?. for high-temperature operation, care must be taken to ensure the combination of ambient temperature, output power dissipation and package thermal resistance does not conspire to raise the device temperature beyond that listed in the absolute maximum ratings . either reduce the output load current or the ambient temperature to keep the part within the limits. figure 3. typical operating circuit lm4040 i load i shunt r s v s v r i shunt + i load pin description pin name function 1+ positive terminal of the shunt reference 2 ? negative terminal of the shunt reference 3 n.c. no connection. leave this pin unconnected or connected to pin 2. chip information transistor count: 60 process: bicmos
