Product details
Overview
MAX6034AEXR33-T from Maxim Integrated is a precision, micropower, low-dropout series voltage reference delivering a stable 3.300V output with ±0.2% initial accuracy, 30ppm/°C max temperature coefficient, and 200mV max dropout at 1mA load - optimized for high-accuracy analog signal chains in space-constrained, battery-powered systems.
For engineers reviewing the MAX6034AEXR33-T datasheet, MAX6034AEXR33-T pinout, MAX6034AEXR33-T application, or MAX6034AEXR33-T equivalent, key selection considerations include its SC70-3 package footprint, supply-current independence from input voltage (≤16µA/V variation), no-output-capacitor stability up to 1µF, and guaranteed operation across –40°C to +85°C.
Technical Context
The MAX6034AEXR33-T employs a proprietary curvature-corrected bandgap core with laser-trimmed thin-film resistors to achieve <30ppm/°C TC and ±0.2% initial tolerance. Its series-mode architecture eliminates external biasing resistors and supports bidirectional load current (1mA source / 200µA sink).
Internally compensated for capacitive loads from 0 to 1µF, it requires no output capacitor for stability - reducing BOM count and PCB area. Supply current remains tightly regulated at 95–125µA over input voltages from 3.5V to 5.5V (VOUT + 200mV to 5.5V), with only 3.8–16µA/V drift.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 3.300V ±0.2% (±6.6mV) at +25°C - enables direct interface with 3.3V ADCs/DACs without gain calibration. |
| Temperature Coefficient | ≤30ppm/°C (max) - ensures ≤±1.0°C-equivalent error over –40°C to +85°C for 16-bit data acquisition. |
| Dropout Voltage | ≤200mV at 1mA load - allows operation from 3.5V supply in low-voltage battery systems (e.g., two-cell Li-ion). |
| Supply Current | 95–125µA (typ. 95µA) - ultra-low quiescent draw extends battery life in always-on sensor nodes. |
| Load Regulation | ≤1.3mV/mA sourcing, ≤8.6mV/mA sinking - maintains reference integrity under dynamic load transients. |
| Noise (0.1–10Hz) | 73µVP-P - low flicker noise critical for high-resolution DC measurements and precision instrumentation. |
| Capacitive Load Stability | 0–1µF - eliminates need for output capacitor, simplifying layout in ultra-dense portable designs. |
Pinout & Package
Package: SC70-3 (3-pin surface-mount, 1.25mm × 0.85mm × 0.55mm height), JEDEC MO-203AA compliant, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN | Supply voltage input | Accepts 3.5V to 5.5V; internal regulation rejects line ripple ≥76dB at 120Hz; no external bypass required but 0.1µF ceramic improves transient response. |
| 2 - OUT | Precision reference voltage output | Delivers 3.300V with <100ppm hysteresis; stable driving 0–1µF capacitive loads; sinks 200µA or sources 1mA without oscillation. |
| 3 - GND | Analog ground reference | Must be connected to clean system ground plane; separates reference return from noisy digital/power grounds to preserve accuracy. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-small SC70-3 package | 1.25mm × 0.85mm footprint saves >60% board area vs. SOT23-3 - critical for handheld medical and IoT sensors. |
| No output capacitor required | Internal compensation eliminates external COUT, reducing component count and eliminating capacitor aging/tolerance drift effects. |
| Supply-current independence | ΔIIN/ΔVIN ≤16µA/V - enables accurate current budgeting across varying battery voltage (e.g., 4.2V → 3.5V discharge). |
| Low dropout at full load | 200mV max at 1mA - supports operation from single Li-ion cell (3.0V min) while powering 3.3V ADCs with margin. |
| Extended temperature range | –40°C to +85°C operation with full spec guarantee - suitable for industrial control and automotive cabin electronics. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADR3433ARJZ-R7 | 3.3V output, ±0.1% initial accuracy, 10ppm/°C TC, 180µA supply current, SOT23-3 package (2.9mm × 1.6mm). | Larger footprint; lower TC but higher supply current; requires 1µF output cap for stability. | Preferred where ultra-low TC dominates over size/power; not drop-in due to larger package and capacitor requirement. |
| REF3033AIDBZR | 3.3V output, ±0.2% initial accuracy, 50ppm/°C TC, 40µA supply current, SOT23-3 package. | Lower quiescent current but higher TC; unstable above 10nF load capacitance; no sink capability. | Selected for ultra-low-power wake-up circuits where TC tolerance >50ppm/°C is acceptable and load is purely sourcing. |
Compared with ADR3433ARJZ-R7 and REF3033AIDBZR, the MAX6034AEXR33-T uniquely balances ultra-small SC70-3 size, 30ppm/°C TC, bidirectional load drive, and capacitor-free stability - making it optimal for miniaturized, battery-operated precision analog systems where board area and transient robustness are critical.

FAQ
What is the maximum input voltage for MAX6034AEXR33-T?
The absolute maximum input voltage for MAX6034AEXR33-T is +6.0V referenced to GND. However, the recommended operating range is (VOUT + 200mV) to 5.5V - i.e., 3.5V to 5.5V. Exceeding 5.5V may degrade long-term reliability or violate safe operating area limits, even if within absolute max ratings.
Does MAX6034AEXR33-T require an output capacitor for stability?
No, MAX6034AEXR33-T is internally compensated and stable with output capacitance from 0 to 1µF. An external capacitor is optional and only recommended to improve transient response in applications with rapid load or supply changes - it is never required for stability.
Can MAX6034AEXR33-T sink current, and how much?
Yes, MAX6034AEXR33-T can sink up to 200µA while maintaining output regulation within specification. This bidirectional capability supports active pull-down in precision DAC buffers or current-sinking bias networks - unlike many references limited to sourcing only.
What is the typical turn-on settling time for MAX6034AEXR33-T?
The typical turn-on settling time for MAX6034AEXR33-T is 200µs to within 0.1% of final output voltage when COUT = 50pF. Settling time increases with larger load capacitance or lower input voltage margin; worst-case (min dropout, max load) may reach 1.25ms.
Is MAX6034AEXR33-T suitable for automotive under-hood applications?
MAX6034AEXR33-T is specified for –40°C to +85°C operation and meets industrial temperature requirements, but it is not AEC-Q200 qualified or rated for under-hood automotive use (which typically requires –40°C to +125°C). It is appropriate for cabin electronics, infotainment, or ADAS subsystems operating within its rated range.
