Product details
Overview
MAX6034BEXR33-T from Maxim Integrated is a precision, low-dropout, micropower series voltage reference delivering 3.300V output with ±0.4% initial accuracy, 75ppm/°C max temperature coefficient, and 200mV max dropout at 1mA load - optimized for space-constrained, battery-powered data-acquisition and industrial control systems.
For engineers reviewing the MAX6034BEXR33-T datasheet, MAX6034BEXR33-T pinout, MAX6034BEXR33-T application, or MAX6034BEXR33-T equivalent, this page provides verified electrical parameters, SC70-3 package details, load-capacitance stability up to 1µF, supply-current independence from input voltage (≤16µA/V), and real-world selection guidance against comparable voltage references.
Technical Context
The MAX6034BEXR33-T implements a proprietary curvature-corrected bandgap core with laser-trimmed thin-film resistors, enabling tight initial accuracy and low thermal drift. Its series-mode architecture eliminates external biasing resistors and supports sourcing up to 1mA and sinking up to 200µA.
Internally compensated for stability across 0–1µF load capacitance, it operates from (VOUT + 200mV) to 5.5V input, draws only 95–125µA quiescent current, and maintains ≤100ppm temperature hysteresis and 90ppm/1000hr long-term stability - critical for high-resolution ADC reference applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 3.300V ±0.4% (±13.2mV) at +25°C - sets absolute accuracy floor for 12-bit+ data converters |
| Temp Coefficient | 75ppm/°C max - limits full-range drift to ±6.3mV over -40°C to +85°C |
| Dropout Voltage | 200mV max at 1mA load - enables operation from 3.5V supply in 3.3V systems |
| Supply Current | 95–125µA typical - ultra-low power suitable for multi-year battery life |
| Line Regulation | 300µV/V max - ensures <±0.1% output shift per volt of input variation |

| 2 - OUT | Reference Voltage Output | Provides regulated 3.300V; sources up to 1mA / sinks up to 200µA; stable with 0–1µF load capacitance |
| 3 - GND | Ground Reference | Low-impedance return path; must be connected directly to system ground plane for noise immunity |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-small SC70-3 package | Saves >50% board area vs. SOT23-3; compatible with fine-pitch automated assembly |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| REF3033AIDBZR | 3.3V, ±0.2% initial accuracy, 50ppm/°C, 120µA IQ, SOT23-3 package | Higher accuracy and lower tempco, but larger footprint and requires 1µF output cap for stability | Choose REF3033AIDBZR when 0.2% accuracy is mandatory and board space allows SOT23-3 |
| ADR3433ARJZ-R7 | 3.3V, ±0.1% initial accuracy, 30ppm/°C, 125µA IQ, SOT23-5 (with enable) | Superior specs and shutdown mode, but 5-pin SOT23 increases routing complexity and cost | Choose ADR3433ARJZ-R7 for highest precision and power-gating capability in non-space-constrained designs |
Compared with REF3033AIDBZR and ADR3433ARJZ-R7, the MAX6034BEXR33-T trades minor accuracy and tempco degradation for significantly smaller SC70-3 size, zero-output-capacitor operation, and proven stability in ultra-low-power, high-density portable systems - making it optimal where board area and component count are primary constraints.

FAQ
What is the maximum input voltage for MAX6034BEXR33-T?
The MAX6034BEXR33-T supports an input voltage range from (VOUT + 200mV) = 3.5V minimum to 5.5V maximum. Absolute maximum rating is 6.0V on the IN pin. Exceeding 5.5V may degrade long-term reliability or violate line-regulation specifications, so operation within the 3.5V–5.5V range is recommended for full parameter compliance.
Does MAX6034BEXR33-T require an output capacitor?
No, the MAX6034BEXR33-T is internally compensated and stable with load capacitance from 0 to 1µF - no output capacitor is required. Adding one (e.g., 100nF ceramic) can improve transient response in high-dynamic-load applications, but it is optional and not needed for basic stability or accuracy.
What is the temperature hysteresis specification for MAX6034BEXR33-T?
The MAX6034BEXR33-T has a temperature hysteresis of 100ppm - defined as the change in output voltage at +25°C after cycling the device from -40°C to +85°C and back. This value is consistent across the MAX6034 family and reflects mechanical stress effects on the bandgap core, independent of initial accuracy grade.
How does the supply current of MAX6034BEXR33-T vary with input voltage?
The MAX6034BEXR33-T exhibits supply-current variation of ≤16µA/V across its input range (3.5V to 5.5V). At 5.5V input, typical IIN is 125µA; at 3.5V, it drops to ~95µA. This near-constant current behavior simplifies power budgeting and avoids load-dependent supply ripple in sensitive analog circuits.
Can MAX6034BEXR33-T sink current, and how much?
Yes, the MAX6034BEXR33-T can sink up to 200µA while maintaining regulation. This capability supports biasing of external circuitry (e.g., pull-down networks or current-steering DACs) and improves system-level fault tolerance - unlike many shunt references that cannot sink current at all.
