Product details
Overview
MAX6037CAUK41+T from Maxim Integrated is a low-dropout, micropower series-mode voltage reference with fixed 4.096V output, ±0.5% initial accuracy (Grade C), 50ppm/°C max temperature coefficient, 2.5V–5.5V input range, and active-low shutdown consuming ≤500nA. It sources/sinks ±5mA, supports 0.02µF–1µF capacitive loads, and targets precision analog front-ends in battery-powered instrumentation.
For engineers reviewing the MAX6037CAUK41+T datasheet, MAX6037CAUK41+T pinout, MAX6037CAUK41+T application, or MAX6037CAUK41+T equivalent, this page delivers verified electrical specs, automotive-grade (-40°C to +125°C) thermal behavior, SOT23-5 package details, and real-world selection guidance for high-accuracy voltage referencing.
Technical Context
The MAX6037CAUK41+T operates as a series-mode shunt-regulated reference with internal bandgap core and buffered output stage. Its shutdown logic is active-low, requiring SHDN ≤0.8V (at VIN ≥4.3V) to enter ultra-low-current mode (<500nA), while VSHDN ≥2.0V enables regulation.
It maintains stability across 0.02µF–1µF output capacitance without external compensation and achieves 4.096V output with 133ppm long-term drift over 1000 hours at +25°C. Dropout voltage remains ≤410mV at 5mA source current, enabling operation down to VIN = 4.3V (VOUT + 0.2V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 4.096V ±0.5% (max initial error at +25°C; Grade C) |
| Tempco | 50ppm/°C max (ensures ≤±0.5% output drift over -40°C to +125°C) |
| Quiescent Current | 210µA–275µA (enables >1-year battery life in µA-level systems) |
| Shutdown Current | ≤500nA (reduces standby power by >400× vs active mode) |
| Dropout Voltage | ≤410mV at 5mA load (supports operation from 4.3V supply with full 4.096V output) |
| Load Drive | ±5mA sourcing/sinking capability (drives ADC references, op-amp bias networks) |
| Capacitive Stability | Stable with 0.02µF–1µF output capacitor (no ESR requirement; simplifies layout) |
Pinout & Package
MAX6037CAUK41+T is housed in a 5-pin SOT23-5 package (U5-2 code, top mark AEJH), with lead-free finish and tape-and-reel packaging. The package measures 2.9mm × 1.6mm × 1.1mm and is rated for -40°C to +125°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (I.C.) | Internally connected | No external connection required; unused pin for fixed-output variants |
| 2 (GND) | Ground reference | Primary return path for supply, output, and shutdown currents; must be low-impedance |
| 3 (SHDN) | Active-low enable control | Pull ≤0.8V to disable output and reduce supply current to ≤500nA |
| 4 (IN) | Supply input | Accepts 2.5V–5.5V; requires 0.1µF bypass capacitor to GND for noise immunity |
| 5 (OUT) | Precision reference output | Delivers stable 4.096V; connect 0.02µF–1µF capacitor to GND for transient stability |

FAQ
What is the maximum input voltage for MAX6037CAUK41+T?
The absolute maximum input voltage for MAX6037CAUK41+T is +6V, but the functional supply range is 2.5V to 5.5V. For reliable operation at 4.096V output, minimum input is 4.3V (VOUT + 0.2V). Exceeding 5.5V risks permanent damage per Absolute Maximum Ratings.
Does MAX6037CAUK41+T require an external capacitor on the output?
Yes, MAX6037CAUK41+T requires an output capacitor between 0.02µF and 1µF connected from OUT to GND for stability across all load conditions. This capacitor suppresses transients and ensures phase margin; ceramic types are recommended for low ESR.
What is the typical turn-on settling time for MAX6037CAUK41+T?
MAX6037CAUK41+T achieves 0.1% output accuracy in 3.2ms after SHDN transitions from low to high (with COUT = 0.02µF and VIN = 5V), as specified in the Electrical Characteristics table for the 4.096V variant. This ensures fast wake-up in duty-cycled systems.
Can MAX6037CAUK41+T drive a 5mA load while maintaining accuracy?
Yes, MAX6037CAUK41+T can source and sink up to ±5mA while maintaining output accuracy within its specified load regulation (≤0.212%/mA sinking, ≤0.027%/mA sourcing at 1mA–5mA). Dropout remains ≤410mV at full 5mA source current.
Is MAX6037CAUK41+T pin-compatible with other MAX6037 variants?
Yes, all MAX6037 variants-including MAX6037CAUK41+T-use identical 5-pin SOT23-5 (U5-2) packaging and pinout. Pin 1 is internally connected (I.C.), Pin 2 is GND, Pin 3 is SHDN, Pin 4 is IN, and Pin 5 is OUT. Only the output voltage and grade differ across variants.
