Product details
Overview
The MAX6030AEUR-T from Analog Devices is a precision, low-dropout, micropower series-mode voltage reference delivering a stable 3.000V output with ±0.2% initial accuracy, <15ppm/°C temperature coefficient, and 100mV dropout at 500μA load current. It operates from (VOUT + 200mV) to 12.6V supply, draws only 35μA max quiescent current, and supports bidirectional 500μA load current-ideal for battery-powered data acquisition and industrial sensor front-ends.
For engineers reviewing the MAX6030AEUR-T datasheet, MAX6030AEUR-T pinout, MAX6030AEUR-T application, or MAX6030AEUR-T equivalent, key selection criteria include its SOT23-3 package footprint, supply-current independence from VIN (0.8μA/V variation), capacitive-load stability up to 2.2nF without external compensation, and guaranteed performance over –40°C to +85°C.
Technical Context
This device implements a curvature-corrected bandgap core with laser-trimmed thin-film resistors to achieve <15ppm/°C TC and ±0.2% initial accuracy across –40°C to +85°C. Its series-mode architecture eliminates the need for an external bias resistor and enables ultra-low, supply-voltage-independent quiescent current.
Internally compensated for stability with 0–2.2nF load capacitance, it delivers 0.14μV/μA load regulation (sourcing) and 20μV/V line regulation while maintaining 80dB ripple rejection at 120Hz-enabling direct integration into high-resolution ADC reference paths and low-noise analog signal chains.

FAQ
What is the maximum load current the MAX6030AEUR-T can source or sink?
The MAX6030AEUR-T can source or sink up to ±500μA while maintaining regulation and specified accuracy. This capability allows direct driving of ADC reference inputs, op-amp bias networks, or small logic loads without external buffering. Exceeding ±500μA may cause output voltage deviation beyond the 0.2% initial accuracy specification.
Does the MAX6030AEUR-T require an external output capacitor for stability?
No, the MAX6030AEUR-T is internally compensated and stable with output capacitance ranging from 0 to 2.2nF. An external capacitor is optional and recommended only in applications subject to large load or supply transients to improve transient response-eliminating it saves PCB area and BOM cost in space-critical designs.
What is the minimum input voltage required for the MAX6030AEUR-T to regulate properly?
The MAX6030AEUR-T requires a minimum input voltage of VOUT + 200mV = 3.2V to maintain regulation at full 500μA load. At lighter loads, it can operate closer to 3.0V, but 3.2V is the guaranteed minimum across temperature and process variation per datasheet specifications.
How does the supply current of the MAX6030AEUR-T vary with input voltage?
The MAX6030AEUR-T exhibits only 0.8μA/V variation in quiescent supply current over its 3.2V–12.6V input range. This near-constant current draw-max 35μA-simplifies power budgeting in systems with variable supply rails and maximizes battery efficiency compared to shunt references whose current scales with VIN.
Is the MAX6030AEUR-T pin-compatible with other devices in the MAX60xx family?
Yes, all MAX60xx devices-including MAX6012, MAX6021, MAX6025, MAX6030, MAX6041, MAX6045, and MAX6050-share identical SOT23-3 pinout (IN, OUT, GND) and package dimensions. This enables drop-in replacement across output voltages (1.247V to 5.000V) without PCB layout changes, provided input voltage and load requirements are verified.
