Datasheet Maxim MAX6138 — 数据表

19-2090; Rev 2; 4/04 0.1%, 25ppm, SC70 Shunt Voltage Reference
with Multiple Reverse Breakdown Voltages
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 60µA 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. Applications
