Product details
Overview
MAX6133A30+T from Maxim Integrated is a high-precision, low-power, low-dropout series voltage reference delivering 3.000V output with ±0.04% initial accuracy (A-grade SO package), 3ppm/°C max temperature coefficient, and 200mV max dropout voltage. It operates from 3.2V to 12.6V supply, draws only 40µA quiescent current, and supports up to 15mA source current - ideal for precision A/D converters and portable instrumentation.
For engineers reviewing the MAX6133A30+T datasheet, MAX6133A30+T pinout, MAX6133A30+T application, or MAX6133A30+T equivalent, this page delivers verified electrical specs, SO-8 package layout, real-world load/line regulation behavior, noise performance (24µVP-P, 0.1Hz–10Hz), and validated alternatives for high-accuracy analog signal chains.
Technical Context
The MAX6133A30+T is a bandgap-based series-mode voltage reference using laser-trimmed thin-film resistors and post-package trimming to achieve ±0.04% initial accuracy and 3ppm/°C tempco over –40°C to +125°C. Its architecture eliminates external biasing components and enables stable operation with 0.1µF to 100µF output capacitance.
It features ultra-low quiescent current (40µA typ., independent of input voltage), excellent line regulation (≤30µV/V), and load regulation (≤0.06mV/mA), making it suitable for battery-powered systems where supply efficiency and long-term stability (40ppm @ 1000h) are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 3.000V ±0.04% at +25°C - ensures ≤1.2mV absolute error in 14-bit DAC reference applications |
| Tempco | 3ppm/°C max (–40°C to +125°C) - supports ≤0.009% full-scale drift across industrial temperature range |
| Dropout Voltage | 200mV max at 10mA - enables operation from 3.2V supply while maintaining 3.0V output |
| Quiescent Current | 40µA typical - draws <12µW from 3V supply, extending battery life in handheld instruments |
| Noise (0.1–10Hz) | 24µVP-P - contributes <0.0008% of 3V full scale, critical for 16-bit+ data acquisition |
| Load Regulation | 0.06mV/mA max - maintains <0.9mV shift over 15mA output swing, supporting dynamic ADC reference loads |
| Line Regulation | 30µV/V max - limits output variation to <90µV over 3.2–12.6V input range |
Pinout & Package
MAX6133A30+T is housed in an 8-pin SO (SOIC-N) package per MS012 outline: 5.00mm × 4.00mm × 1.50mm body, 1.27mm pitch, gull-wing leads. Pin 1 is marked by notch or dot; pins 1, 3, and 7 are no-connect (N.C.), pins 5 and 8 are internally connected (I.C.) and must remain unconnected, pin 2 is IN, pin 4 is GND, and pin 6 is OUT.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 7 | No Connection (N.C.) | Not bonded internally; leave floating or tie to GND for mechanical stability - no electrical function |
| 2 | IN | Positive supply input; requires ≥3.2V for regulation; decoupling capacitor (0.1µF) recommended at pin |
| 4 | GND | Analog ground reference; connect directly to low-impedance system ground plane |
| 5, 8 | Internally Connected (I.C.) | Internal bond wires only; must not be externally connected - risk of damage or parametric shift |
| 6 | OUT | Stable 3.000V reference output; requires ≥0.1µF ceramic capacitor to GND for stability and transient response |
Key Features
| Feature | Design Value |
|---|---|
| Low-tempco bandgap core | 3ppm/°C max over –40°C to +125°C - enables 16-bit accuracy without calibration in wide-temperature environments |
| Series-mode architecture | 40µA quiescent current, independent of VIN - eliminates wasted supply current seen in shunt references |
| Laser-trimmed thin-film resistors | ±0.04% initial accuracy - reduces system-level calibration burden in production test |
| Wide supply range | 3.2V to 12.6V input - supports direct connection to unregulated Li-ion or multi-rail power supplies |
| Capacitive load stability | Stable with 0.1µF to 100µF output capacitance - accommodates both low-noise (10µF) and fast-transient (0.1µF) design needs |
Applications
| Precision A/D Conversion | Portable Instrumentation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADR3430ARZ | 3.0V output, ±0.1% initial accuracy, 10ppm/°C max tempco, 35µA IQ, SOT-23-5 package | Higher tempco and accuracy tolerance; smaller footprint but lower precision | Choose when board space is constrained and 12-bit accuracy suffices; not suitable for 14-bit+ systems |
| REF3330AIDBVR | 3.0V output, ±0.2% initial accuracy, 50ppm/°C max tempco, 3.9µA IQ, SOT-23-5 | Ultra-low quiescent current but significantly degraded accuracy and stability | Prefer for sub-10µA battery-critical designs where 10-bit resolution is acceptable; avoid for metrology-grade use |
Compared with ADR3430ARZ and REF3330AIDBVR, MAX6133A30+T delivers superior initial accuracy (0.04% vs. 0.1%/0.2%), lower tempco (3ppm/°C vs. 10/50ppm/°C), and higher output drive (15mA vs. 10mA), justifying its use in 14–16-bit data acquisition where reference error dominates system ENOB.

FAQ
What is the maximum output current capability of the MAX6133A30+T?
The MAX6133A30+T supports up to 15mA of source current while maintaining specified accuracy and regulation. This is confirmed in the Electrical Characteristics table under "Output Source-Current Capability" and validated across temperature (-40°C to +125°C) with load regulation guaranteed to 0.06mV/mA. Exceeding 15mA may cause dropout or accuracy degradation.
Does the MAX6133A30+T require an input bypass capacitor?
While not strictly mandatory, the MAX6133A30+T datasheet recommends a 0.1µF ceramic capacitor placed as close as possible to the IN pin for optimal line-transient performance. Without it, line rejection degrades - especially at higher frequencies - potentially introducing ripple into the 3.000V reference output during supply fluctuations.
Can the MAX6133A30+T be used with a 3.0V supply?
No - the MAX6133A30+T requires a minimum input voltage of 3.2V to maintain regulation at 3.000V output. At VIN = 3.0V, the device enters dropout, causing output voltage to drop below specification. The 200mV max dropout voltage defines the minimum headroom needed: VIN ≥ VOUT + VDO = 3.0V + 0.2V = 3.2V.
What is the output voltage noise of the MAX6133A30+T, and how is it measured?
The MAX6133A30+T exhibits 24µVP-P (0.1Hz to 10Hz) and 15µVRMS (10Hz to 1kHz) output voltage noise. These values are measured under standard conditions (VIN = 5V, CLOAD = 0.1µF, IOUT = 0, TA = +25°C) and reflect true low-frequency noise critical for high-resolution DC measurements.
Is the MAX6133A30+T pin-compatible with other MAX6133 variants?
Yes - all MAX6133 variants (including MAX6133A25+T, MAX6133A41+T, MAX6133A50+T) share identical 8-pin SO packaging and pinout. Only the output voltage and grade-specific parameters (initial accuracy, tempco) differ; no PCB redesign is needed when swapping within the same package option.
