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 applica-

tions, 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.

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.

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.
