Product details
Overview
MAX6133A50+T from Maxim Integrated is a precision series-mode voltage reference delivering 5.000V output with ±0.04% initial accuracy (A-grade SO), 3ppm/°C max temperature coefficient, and 200mV max dropout voltage. It operates from 5.2V to 12.6V input, supplies up to 15mA load current, and consumes only 40µA quiescent current - ideal for high-resolution ADC/DAC biasing in portable instrumentation.
For engineers reviewing the MAX6133A50+T datasheet, MAX6133A50+T pinout, MAX6133A50+T application, or MAX6133A50+T equivalent, this page provides verified technical context, package-specific pin definitions, real-world application constraints, and validated alternative options for precision analog signal chains requiring stable 5V reference performance across -40°C to +125°C.
Technical Context
The MAX6133A50+T is a bandgap-based series 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 series architecture eliminates external current-setting resistors and enables low-noise operation (40µVP-P, 0.1Hz–10Hz) without shunt-path power loss.
It features guaranteed line regulation (≤50µV/V), load regulation (≤0.10mV/mA), and thermal hysteresis of 120ppm. The device maintains stability with output capacitance from 0.1µF to 100µF and achieves <1ms turn-on settling to ±0.01% of final value under typical conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.000V ±0.02% (±1mV) at +25°C - sets absolute scaling for 14-bit+ data converters. |
| Initial Accuracy | ±0.04% max (±2mV) at +25°C - eliminates need for system-level calibration in portable test equipment. |
| Tempco | 3ppm/°C max (-40°C to +125°C) - supports ≤1LSB error in 16-bit systems over full industrial range. |
| Dropout Voltage | 200mV max at 10mA load - enables operation from 5.2V supply with 300mV headroom for LDO pre-regulation. |
| Quiescent Current | 40µA typical, ≤85µA over temperature - extends battery life in handheld multimeters and sensor nodes. |
| Output Noise | 40µVP-P (0.1Hz–10Hz), 26µVRMS (10Hz–1kHz) - preserves SNR in precision 24-bit sigma-delta ADCs. |
| Load Regulation | 0.01–0.10mV/mA - ensures <50µV shift across 0–15mA load, critical for dynamic DAC reference stability. |
Pinout & Package
MAX6133A50+T is supplied in an 8-pin SO (SOIC-N) package measuring 4.90mm × 3.90mm × 1.75mm, compliant with JEDEC MS-012. Pin 1 is marked by a beveled corner; 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 5.2V 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 plane. |
| 5, 8 | I.C. | Internally connected - not for external use; leave unconnected per datasheet directive. |
| 6 | OUT | Precision 5.000V reference output - requires ≥0.1µF ceramic capacitor to GND for stability and transient immunity. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADR4550BRZ | 5.0V output, ±0.02% initial accuracy, 3ppm/°C tempco, 950µA quiescent current | Higher power consumption limits use in battery-powered devices; superior long-term stability (15ppm/1000h) | Select ADR4550BRZ when ultimate aging performance outweighs battery life concerns in lab-grade equipment. |

FAQ
What is the maximum load current supported by the MAX6133A50+T?
The MAX6133A50+T guarantees stable operation with output source currents up to 15mA. Load regulation is specified at 0.01–0.10mV/mA across this range, ensuring output voltage deviation remains within ±1.5mV. Exceeding 15mA may degrade accuracy and increase dropout voltage beyond the 200mV maximum specification.
Does the MAX6133A50+T require an input bypass capacitor?
Yes, the MAX6133A50+T requires a 0.1µF ceramic capacitor between IN and GND for optimal line-transient performance. This capacitor must be placed as close as possible to the IN pin. While the device will operate without it, omitting the capacitor increases susceptibility to supply noise and degrades PSRR above 10kHz.
Can the MAX6133A50+T be used with output capacitance larger than 0.1µF?
Yes, the MAX6133A50+T is stable with output capacitance from 0.1µF up to 100µF. Larger capacitors (e.g., 10µF) improve transient response during step-load changes and reduce overshoot, especially in DAC reference applications. However, turn-on settling time increases proportionally - e.g., 1000µs with 10µF vs. 500µs with 0.1µF.
What is the thermal hysteresis specification for the MAX6133A50+T?
The MAX6133A50+T exhibits 120ppm thermal hysteresis - defined as the change in output voltage at +25°C before and after cycling from -40°C to +125°C. This value is identical for both SO and µMAX packages and represents non-recoverable stress-induced offset in the bandgap core.
Is the MAX6133A50+T pin-compatible with other MAX6133 variants?
Yes, all MAX6133 variants including MAX6133A50+T share identical 8-pin SO (MS-012) pinout and footprint. Output voltage (2.5V/3.0V/4.096V/5.0V) and grade (A/B) are encoded in the suffix; no PCB layout change is needed when substituting within the same package type.
