Product details
Overview
The MAX6133AASA30 from Maxim Integrated is a precision series voltage reference delivering 3.000V output with ±0.04% initial accuracy (A-grade SO), 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 high-resolution ADC/DAC biasing in portable instrumentation.
For engineers reviewing the MAX6133AASA30 datasheet, MAX6133AASA30 pinout, MAX6133AASA30 application, or MAX6133AASA30 equivalent, this device is selected for low-power, high-stability analog signal chains requiring sub-10ppm/°C drift, minimal supply overhead, and guaranteed load regulation under 0.06mV/mA across -40°C to +125°C.
Technical Context
The MAX6133AASA30 uses bandgap-based series-mode architecture with 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 low-noise design delivers 24µVP-P (0.1Hz–10Hz) and 15µVRMS (10Hz–1kHz) output noise at 3.000V output.
It features wide input range (3.2V–12.6V), excellent line regulation (≤30µV/V), and load regulation (≤0.06mV/mA), enabling stable operation across varying supply and load conditions without external compensation. Turn-on settling time is 600µs to ±0.01% of final value.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 3.000V ±0.04% (max) at +25°C - ensures ≤1.2mV absolute error for 14-bit DAC reference applications |
| Tempco | 3ppm/°C (max) over -40°C to +125°C - guarantees ≤0.9mV drift across full industrial temperature range |
| Dropout Voltage | 200mV (max) at 10mA load - enables operation with only 3.2V supply for 3.0V output, minimizing headroom loss |
| Quiescent Current | 40µA (typ), ≤85µA (max) over temperature - extends battery life in handheld instruments and remote sensors |
| Noise (0.1–10Hz) | 24µVP-P - supports <16-bit effective resolution in precision data acquisition systems |
| Load Regulation | 0.003–0.06mV/mA - maintains output stability despite dynamic load changes up to 15mA |
| Line Regulation | 2–30µV/V - rejects supply ripple without additional filtering in noisy power environments |
Pinout & Package
MAX6133AASA30 is housed in an 8-pin SO (Small Outline) package per JEDEC MS-012, with 150-mil body width, gull-wing leads, and RoHS-compliant finish. Pin 1 is marked by notch or dot; pins are numbered counterclockwise.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 7 | No Connection (N.C.) | Internally unconnected - must remain floating or tied to GND; no electrical function |
| 2 | IN | Positive supply input - accepts 3.2V to 12.6V; requires 0.1µF ceramic bypass capacitor placed adjacent to pin |
| 4 | GND | Analog ground reference - common return for IN, OUT, and load; must be low-impedance |
| 5, 8 | I.C. | Internally connected - not for external use; leave unconnected per datasheet |
| 6 | OUT | Precision 3.000V reference output - requires ≥0.1µF ceramic capacitor to GND for stability; drives up to 15mA |
Key Features
| Feature | Design Value |
|---|---|
| Low-tempco precision | 3ppm/°C max over -40°C to +125°C - meets tight drift requirements for industrial process control |
| Ultra-low quiescent current | 40µA typical - enables multi-year battery operation in wireless sensor nodes |
| Low-dropout operation | 200mV max at 10mA - allows direct use from single Li-ion or 3.3V rails without LDO pre-regulation |
| Laser-trimmed accuracy | ±0.04% initial tolerance (A-grade SO) - eliminates system-level calibration for many 14-bit applications |
| Low-noise output | 24µVP-P (0.1–10Hz) - preserves SNR in high-resolution ADC front-ends and precision measurement circuits |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADR3430ARZ | 3.0V output, ±0.1% initial accuracy, 3ppm/°C tempco, 12µA quiescent current, SOT-23-5 package | Lower supply current but higher initial error; smaller footprint but lower output drive (10mA) | Select ADR3430ARZ when board space is critical and load current ≤10mA; verify layout for thermal stability in high-density designs |
| REF3330AIDBVR | 3.0V output, ±0.1% initial accuracy, 10ppm/°C tempco, 3.9µA quiescent current, SOT-23-3 package | Ultra-low power but higher tempco; no separate GND pin - limits noise isolation in mixed-signal layouts | Choose REF3330AIDBVR only for ultra-low-power sensor nodes where tempco <10ppm/°C is acceptable and PCB area is constrained |
Compared with ADR3430ARZ and REF3330AIDBVR, the MAX6133AASA30 offers superior initial accuracy (±0.04% vs. ±0.1%) and tighter tempco (3ppm/°C vs. 10ppm/°C), making it preferred for metrology-grade applications - though its 8-pin SO package requires more board area than SOT-23 alternatives.

FAQ
What is the maximum load current supported by the MAX6133AASA30?
The MAX6133AASA30 supports up to 15mA of output source current while maintaining specified accuracy and regulation. Load regulation is guaranteed at 0.003–0.06mV/mA across -100µA to +15mA, and dropout voltage remains ≤200mV at 10mA. Exceeding 15mA may degrade output stability and increase thermal drift.
Does the MAX6133AASA30 require an input bypass capacitor?
Yes - the MAX6133AASA30 requires a 0.1µF ceramic capacitor placed as close as possible to the IN pin (Pin 2) and GND for optimal line-transient response and stability. While operation without it is possible under static conditions, omitting this capacitor degrades PSRR and increases susceptibility to supply noise, especially in switching power supply environments.
What is the operating temperature range for the MAX6133AASA30?
The MAX6133AASA30 is rated for continuous operation from -40°C to +125°C. All key specifications - including initial accuracy (±0.04%), temperature coefficient (3ppm/°C max), dropout voltage (200mV max), and quiescent current (≤85µA) - are guaranteed across this full industrial temperature range.
Can the MAX6133AASA30 be used with capacitive loads larger than 0.1µF?
Yes - the MAX6133AASA30 is stable with output capacitance from 0.1µF up to 100µF. Larger capacitors (e.g., 10µF) improve transient response to step-load changes and reduce overshoot/undershoot, particularly in DAC reference or fast-settling measurement applications. Ensure the capacitor is ceramic or low-ESR tantalum for best performance.
How does the MAX6133AASA30 compare to shunt voltage references in terms of power efficiency?
The MAX6133AASA30 is a series-mode reference consuming only 40µA quiescent current - independent of load - whereas shunt references draw total current equal to load plus reference bias. This makes the MAX6133AASA30 significantly more efficient, especially at light loads, reducing system power dissipation and extending battery life in portable applications.
