19-2090; Rev 0; 10/01  
0.1%, 25ppm, SC70 Shunt Voltage Reference  
with Multiple Reverse Breakdown Voltages  
General Description  
Features  
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,  
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 surface-mount  
packages.  
Ultra-Small 3-Pin SC70 Package  
0.1% (max) Initial Accuracy  
25ppm/°C (max) Temperature Coefficient  
Guaranteed Over -40°C to +85°C Temperature  
Range  
Wide Operating Current Range: 60µA to 15mA  
Low 28µV  
Output Noise (10Hz to 10kHz)  
RMS  
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 60µA to 15mA shunt-  
current capability with low-dynamic impedance, ensuring  
stable reverse breakdown voltage accuracy over a wide  
range of operating temperatures and currents.  
1.2205V, 2.048V, 2.5V, 3.0V, 4.096V, and 5.0V  
Fixed Reverse Breakdown Voltages  
No Output Capacitors Required  
Stable with Capacitive Loads  
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.
