lm4050/lm4051 50ppm/? precision micropower shunt voltage references with multiple reverse breakdown voltages ______________________________________________________________________________________ 11 detailed description the lm4050/lm4051 shunt references use the bandgap principle to produce a stable, accurate volt- age. the device behaves similarly to an ideal zener diode; a fixed voltage is maintained across its output terminals when biased with 60? to 15ma of reverse current. the lm4050/lm4051 clamps to a voltage of one diode drop below ground when biased with for- ward currents up 10ma. figure 3 shows a typical operating circuit. the lm4050/lm4051 are ideal for providing stable refer- ences from a high-voltage power supply. applications information the lm4050/lm4051s?internal pass transistors are 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 lm4050/lm4051 do not require external capacitors for frequency stability and are stable for any output capacitance. temperature performance the lm4050/lm4051 typically exhibit output voltage temperature coefficients within ?5ppm/?. the polari- ty of the temperature coefficients may be different from one device to another; some may have positive coeffi- cients, and others may have negative coefficients. high temperature operation the maximum junction temperature of the lm4050/ lm4051 is +150?. the maximum operating temperature for the lm4050/lm4051_e_ is +125?. at a maximum load current of 15ma and a maximum output voltage of 5v, the parts dissipate 75mw of power. the power dissi- pation limits of the 3-pin sc70 call for a derating value of 2.17mw/? above +70? and thus for 75mw of power dissipation, the parts self-heat to 35.56? above ambient temperature. if the ambient temperature is +125?, the parts operate at 159.56?, thereby exceeding the maxi- mum junction temperature value of +150?. for high- temperature operation, care must be taken to ensure the combination of ambient temperature, output power dissi- pation, and package thermal resistance does not con- spire to raise the device temperature beyond that listed in the absolute maximum ratings . either reduce the out- put load current or the ambient temperature to keep the part within the limits. figure 3. typical operating circuit lm4050/lm4051 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
