Product details
Overview
MAX6030BEUR+T from Analog Devices is a precision 3.000V series-mode voltage reference in SOT23-3 package, featuring ±0.4% initial accuracy, <20ppm/°C temperature coefficient over –40°C to +85°C, and 100mV dropout at 500μA load. It delivers ultra-low 35μA max quiescent current with 0.8μA/V supply-voltage dependence, enabling high-efficiency operation in battery-powered instrumentation and portable data acquisition systems.
For engineers reviewing the MAX6030BEUR+T datasheet, MAX6030BEUR+T pinout, MAX6030BEUR+T application, or MAX6030BEUR+T equivalent, key selection criteria include output voltage tolerance, temperature drift stability, load regulation (0.14μV/μA sourcing), dropout behavior under varying input voltage, and compatibility with 0–2.2nF capacitive loads without external compensation.
Technical Context
The MAX6030BEUR+T employs a proprietary curvature-corrected bandgap core with laser-trimmed thin-film resistors to achieve low thermal drift and tight initial accuracy. Its series-mode architecture eliminates the need for external biasing resistors and supports bidirectional 500μA output current-sourcing and sinking-without instability.
Internally compensated for capacitive loads up to 2.2nF, it operates across an input range of 3.2V to 12.6V (VOUT + 0.2V min), with line regulation of 20μV/V and load regulation of 0.14μV/μA (sourcing) and 0.18μV/μA (sinking), ensuring stable reference performance in low-noise analog signal chains.
Key Specifications

FAQ
What is the output voltage tolerance of the MAX6030BEUR+T over temperature?
The MAX6030BEUR+T has an initial output voltage of 3.000V ±0.4% at +25°C and a maximum temperature coefficient of 20ppm/°C over –40°C to +85°C. This results in a total output variation of ≤±600μV across the full temperature range, confirmed by the "box method" measurement per datasheet Note 2.
Does the MAX6030BEUR+T require an external output capacitor?
No, the MAX6030BEUR+T is internally compensated and stable with capacitive loads from 0 to 2.2nF. Unlike many references, it does not require an external capacitor for stability-eliminating a common BOM item and saving PCB area in miniaturized designs.
What is the minimum input voltage needed for regulation with the MAX6030BEUR+T?
The MAX6030BEUR+T requires a minimum input voltage of VOUT + 200mV = 3.2V to maintain regulation at full 500μA load. Its dropout voltage is specified as 100mV at 500μA, meaning it regulates stably down to 3.2V input across the full industrial temperature range.
How does the supply current of the MAX6030BEUR+T vary with input voltage?
The MAX6030BEUR+T exhibits a supply current variation of only 0.8μA/V across its 3.2V–12.6V input range. At 3.2V input, typical supply current is ~27μA; at 12.6V, it rises by just ~7.5μA-enabling predictable power budgeting in wide-input-voltage systems.
Can the MAX6030BEUR+T sink and source load current simultaneously?
No-the MAX6030BEUR+T operates in series mode and can either source up to +500μA (to a load connected to GND) or sink up to –500μA (from a load connected to a higher voltage), but not both simultaneously. Its bidirectional capability supports flexible biasing in op-amp and ADC circuits without polarity reversal.
