50ppm/C Precision Micropower Shunt Voltage References with Multiple Reverse Breakdown Voltages
General Description
The LM4050/LM4051 are precision two-terminal, shuntmode, bandgap voltage references available in fixed reverse breakdown voltages of 1.225V, 2.048V, 2.500V, 3.000V, 3.3V, 4.096V, and 5.000V. Ideal for space-critical applications, the LM4050/LM4051 are offered in the subminiature 3-pin SC70 surface-mount packages (1.8mm x 1.8mm), 50% smaller than comparable devices in SOT23 surface-mount package (SOT23 versions are also available). Laser-trimmed resistors ensure excellent initial accuracy. With a 50ppm/C temperature coefficient, these devices are offered in three grades of initial accuracy ranging from 0.1% to 0.5%. The LM4050/LM4051 have a 60A to 15mA shunt-current capability with low dynamic impedance, ensuring stable reverse breakdown voltage accuracy over a wide range of operating temperatures and currents. The LM4050/LM4051 do not require an external stabilizing capacitor while ensuring stability with any capacitive loads. The LM4050/LM4051 specifications are guaranteed over the temperature range of -40C to +125C.

Note 1: All devices are 100% production tested at +25C and are guaranteed by design for TA = TMIN to TMAX, as specified. Note 2: The limit over the full temperature range for the reverse breakdown voltage tolerance is defined as: [VRTOL] [(VR / T) X (maxT) X (VR)] where VR / T is the VR temperature coefficient, maxT is the difference from the +25C reference point to TMIN or TMAX, and VR is the reverse breakdown voltage. The total tolerance over the full temperature range for the different grades where maxT = +100C is shown below: * A grade: 0.6% = 0.1% 50ppm/C 100C * B grade: 0.7% = 0.2% 50ppm/C 100C * C grade: 1.0% = 0.5% 50ppm/C 100C Note 3: Guaranteed by design.

Pin Description
PIN 1 2 3 NAME + - N.C. Positive Terminal of the Shunt Reference Negative Terminal of the Shunt Reference No connection. Leave this pin unconnected or connected to pin 2. FUNCTION
LM4050/LM4051
Detailed Description
The LM4050/LM4051 shunt references use the bandgap principle to produce a stable, accurate voltage. The device behaves similarly to an ideal zener diode; a fixed voltage is maintained across its output terminals when biased with 60A to 15mA of reverse current. The LM4050/LM4051 clamps to a voltage of one diode drop below ground when biased with forward currents up 10mA. Figure 3 shows a typical operating circuit. The LM4050/LM4051 are ideal for providing stable references from a high-voltage power supply.

Figure 3. Typical Operating Circuit
Applications Information
The LM4050/LM4051s' internal pass transistors are used to maintain a constant output voltage (VSHUNT) by sinking the necessary amount of current across a source resistor. The source resistance (RS) is determined from the load current (ILOAD) range, supply voltage (VS) variations, VSHUNT, and desired quiescent current. Choose the value of RS when VS is at a minimum and ILOAD is at a maximum. Maintain a minimum ISHUNT of 60A at all times. The RS value should be large enough to keep ISHUNT less than 15mA for proper regulation when VS is maximum and ILOAD is at a minimum. To prevent damage to the device, ISHUNT should never exceed 20mA. Therefore, the value of RS is bounded by the following equation: [VS(MIN) - VR ] / [60A + ILOAD(MAX)] > RS > [VS(MAX) - VR ] / [20mA + ILOAD(MIN)] Choosing a larger resistance minimizes the total power dissipation in the circuit by reducing the shunt current (PD(TOTAL) = VS ISHUNT). Provide a safety margin to incorporate the worst-case tolerance of the resistor used. Ensure that the resistor's power rating is adequate, using the following general power equation: PDR = ISHUNT (VS(MAX) - VSHUNT)
Temperature Performance
The LM4050/LM4051 typically exhibit output voltage temperature coefficients within 15ppm/C. The polarity of the temperature coefficients 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 LM4050/ LM4051 is +150C. The maximum operating temperature for the LM4050/LM4051_E_ is +125C. At a maximum load current of 15mA and a maximum output voltage of 5V, the parts dissipate 75mW of power. The power dissipation limits of the 3-pin SC70 call for a derating value of 2.17mW/C above +70C and thus for 75mW of power dissipation, the parts self-heat to 35.56C above ambient temperature. If the ambient temperature is +125C, the parts operate at 159.56C, thereby exceeding the maximum junction temperature value of +150C. For hightemperature 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.
Output Capacitance
The LM4050/LM4051 do not require external capacitors for frequency stability and are stable for any output capacitance. TRANSISTOR COUNT: 60 PROCESS: BiCMOS
