0.1%, 25ppm, SC70 Shunt Voltage Reference with Multiple Reverse Breakdown Voltages
General Description
The MAX6138 is a precision, two-terminal shunt mode, bandgap voltage reference available in fixed reverse breakdown voltages of 1.2205V, 2.048V, 2.5V, 3.0V, 3.3V, 4.096V, and 5.0V. Ideal for space-critical applications, the MAX6138 is offered in the subminiature 3-pin SC70 surface-mount package (1.8mm X 1.8mm), 50% smaller than comparable devices in SOT23 surfacemount packages. Laser-trimmed resistors ensure precise initial accuracy. With a 25ppm/C temperature coefficient, the device is offered in three grades of initial accuracy ranging from 0.1% to 0.5%. The MAX6138 has a 60A to 15mA shuntcurrent capability with low-dynamic impedance, ensuring stable reverse breakdown voltage accuracy over a wide range of operating temperatures and currents. The MAX6138 does not require an external stabilizing capacitor while ensuring stability with capacitive loads. The MAX6138 is a higher precision device in a smaller package than the LM4040/LM4050. o Ultra-Small 3-Pin SC70 Package o 0.1% (max) Initial Accuracy o 25ppm/C (max) Temperature Coefficient Guaranteed Over -40C to +85C Temperature Range o Wide Operating Current Range: 60A to 15mA o Low 28VRMS Output Noise (10Hz to 10kHz) o 1.2205V, 2.048V, 2.5V, 3.0V, 3.3V, 4.096V, and 5.0V Fixed Reverse Breakdown Voltages o No Output Capacitors Required o Stable with Capacitive Loads

MAX6138
Detailed Description
The MAX6138 shunt reference uses 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 MAX6138 behaves similarly to a silicon diode when biased with forward currents up to 10mA. Figure 3 shows a typical operating circuit. The MAX6138 is ideal for providing a stable reference from a high-voltage power supply.

MAX6138
Applications Information
The MAX6138's internal pass transistor is 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 X 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) TRANSISTOR COUNT: 70 PROCESS: BiCMOS
Figure 3. Typical Operating Circuit
Output Capacitance
The MAX6138 does not require an external capacitor for operational stability and is stable for any output capacitance.
Temperature Performance
The MAX6138 typically exhibits an output voltage temperature coefficient within 4ppm/C. 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.
