0.1%, 25ppm, SC70 Shunt Voltage Reference with Multiple Reverse Breakdown Voltages MAX6138 General Description Features
The MAX6138 is a precision, two-terminal shunt mode, ♦
Ultra-Small 3-Pin SC70 Package
bandgap voltage reference available in fixed reverse ♦
0.1% (max) Initial Accuracy
breakdown voltages of 1.2205V, 2.048V, 2.5V, 3.0V, 3.3V, 4.096V, and 5.0V. Ideal for space-critical applica- ♦

Guaranteed Over -40°C to +85°C Temperature
SC70 surface-mount package (1.8mm X 1.8mm), 50%
Range
smaller than comparable devices in SOT23 surface- mount packages. ♦
Wide Operating Current Range: 60µA to 15mA
Laser-trimmed resistors ensure precise initial accuracy. ♦
Low 28µVRMS Output Noise (10Hz to 10kHz)
With a 25ppm/°C temperature coefficient, the device is ♦
1.2205V, 2.048V, 2.5V, 3.0V, 3.3V, 4.096V, and 5.0V
offered in three grades of initial accuracy ranging from
Fixed Reverse Breakdown Voltages
0.1% to 0.5%. The MAX6138 has a 60µA to 15mA shunt- current capability with low-dynamic impedance, ensuring ♦
No Output Capacitors Required
stable reverse breakdown voltage accuracy over a wide ♦
Stable with Capacitive Loads
range of operating temperatures and currents. The MAX6138 does not require an external stabilizing
Selector Guide
capacitor while ensuring stability with capacitive loads.
OUTPUT
The MAX6138 is a higher precision device in a smaller
TEMP PIN- PART VOLTAGE
package than the LM4040/LM4050.
