... U APPLICATIONS INFORMATION 1A Adjustable Voltage Reference The circuit in Figure 12 uses the LT1166 in a feedback loop with the LT1431 to make a voltage reference with an “attitude.” This 5V reference can drive 1A and maintain 0.4% tolerance at the output. If other output voltages are desired, external resistors can be used instead of the LT1431’ ...
