Product details
Overview
MAX6029EUK30+T from Maxim Integrated is a micropower, low-dropout series-mode voltage reference delivering 3.000V output with ±0.15% (max) initial accuracy, 30ppm/°C (max) temperature coefficient, and ultra-low 6.75µA (max) supply current. It sources up to 4mA and sinks up to 1mA, operates from 3.2V to 12.6V input, and features 200mV dropout - ideal for precision battery-powered instrumentation and data converters.
For engineers reviewing the MAX6029EUK30+T datasheet, MAX6029EUK30+T pinout, MAX6029EUK30+T application, or MAX6029EUK30+T equivalent, key selection criteria include guaranteed 3.000V output tolerance over –40°C to +85°C, stability with 0–10µF capacitive loads, no external compensation requirement, and SOT23-5 package compatibility with space-constrained PCB layouts.
Technical Context
The MAX6029EUK30+T uses a bandgap-based series architecture with internal compensation, eliminating need for external capacitors while maintaining stability across 0–10µF load capacitance when sourcing and up to 0.4µF when sinking. Its low 200mV dropout enables operation near battery end-of-life in 3.3V systems.
Supply current remains tightly regulated at ≤6.75µA (max) with only 1.5µA/V variation over 3.2V–12.6V input range, and output voltage exhibits ≤140ppm thermal hysteresis and 150ppm long-term drift after 1000 hours - critical for metrology-grade calibration retention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 3.000V ±0.15% at +25°C - ensures 12-bit ADC full-scale error <0.5 LSB over temperature |
| Tempco | 30ppm/°C (max) - supports ≤1 LSB error in 14-bit systems across –40°C to +85°C |
| Supply Current | 6.75µA (max) - enables >10-year battery life in 10µA-sleep IoT sensors |

| Load Regulation | 0.1–0.6 µV/µA - maintains <±100µV shift from 0 to 4mA sourcing |
| Noise (10Hz–1kHz) | 161µVRMS - suitable for 16-bit SAR ADCs without additional filtering |
| PSRR | 37dB at 120Hz - suppresses ripple from switching regulators feeding precision analog stages |
Pinout & Package
MAX6029EUK30+T is housed in a lead-free, RoHS-compliant 5-pin SOT23 package (outline 21-0057), occupying 70% less board area than comparable SO-8 voltage references.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN | Positive supply input (3.2V–12.6V); no bypass capacitor required but 0.1µF improves transient response |
| 2 | GND | Analog ground reference; must be low-impedance connection to minimize noise coupling |
| 3, 4 | N.C. | No internal connection; may be left floating or tied to GND for mechanical stability |
| 5 | OUT | Stable 3.000V reference output; drives capacitive loads up to 10µF without oscillation |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 6.75µA (max) - extends coin-cell lifetime beyond 10 years in always-on sensing nodes |
| Internal compensation | No external capacitor needed - eliminates layout sensitivity and reduces BOM count by one component |
| Capacitive load tolerance | Stable with 0–10µF output capacitance - accommodates ceramic, tantalum, and polymer caps without phase margin loss |
| Low thermal hysteresis | 140ppm - preserves calibration integrity after repeated thermal cycling in field-deployed instruments |
| Wide supply range | 3.2V–12.6V - supports single-supply operation from Li-ion, 2xAA, or unregulated wall adapters |
