Product details
Overview
MAX6165AESA+ from Maxim Integrated is a precision, low-dropout, micropower series voltage reference delivering a stable 5.000V output with ±2mV initial accuracy and 5ppm/°C (max) temperature coefficient over -40°C to +85°C. It sources up to 5mA load current, features 200mV max dropout at 1mA, draws only 100µA typical quiescent current, and operates from VOUT + 0.2V to 12.6V input-ideal for high-accuracy ADC biasing in portable 5V systems.
For engineers reviewing the MAX6165AESA+ datasheet, MAX6165AESA+ pinout, MAX6165AESA+ application, or MAX6165AESA+ equivalent, key selection criteria include its guaranteed 5.000V output tolerance, ultra-low thermal drift, supply-current independence (≤8µA/V variation), no-external-capacitor stability, and SO-8 package compatibility with space-constrained battery-powered designs.
Technical Context
The MAX6165AESA+ employs a proprietary curvature-correction circuit and laser-trimmed thin-film resistors to achieve 5ppm/°C max TCVOUT and ±2mV initial accuracy. Its BiCMOS process enables precise bandgap core operation with 125ppm output hysteresis and 80ppm/1000hr long-term stability.
As a three-terminal series-mode reference, it eliminates external bias resistors and compensation capacitors. Input regulation is specified from VOUT + 0.2V (i.e., 5.2V min for 5V output), with line regulation of 180–400µV/V and load regulation of 0.6–0.9mV/mA (sourcing) and 2.4–8.0mV/mA (sinking).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.000V ±2mV at +25°C - ensures direct compatibility with 5V ADC full-scale references without calibration. |
| Temp Coefficient | 5ppm/°C (max) - limits output drift to ≤±0.425mV across -40°C to +85°C operating range. |
| Dropout Voltage | 200mV (max) at 1mA - allows operation from 5.2V supply, enabling use with low-headroom LDOs or partially discharged batteries. |
| Quiescent Current | 100µA (typ), ≤120µA (max) - minimizes standby power in always-on sensor nodes and portable instrumentation. |
| Noise (0.1–10Hz) | 60µVp-p - supports 16-bit+ resolution in precision data acquisition without added filtering. |
| Supply Current Variation | ≤8µA/V - ensures predictable current draw across 5.2–12.6V input range, simplifying power budgeting. |
| Ripple Rejection | 65dB at 120Hz - suppresses AC line noise on unregulated supplies feeding analog front-ends. |
Pinout & Package
MAX6165AESA+ is housed in an 8-pin SO (Small Outline) package per outline 21-0041, RoHS-compliant with lead-free finish. Pin 1 is marked by a beveled corner or dot; pins 1, 3, 5, 7, and 8 are No Connect (N.C.), internally unconnected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pin 2) | Input Supply Terminal | Accepts 5.2V–12.6V input; requires 0.1µF ceramic bypass capacitor near pin for optimal line-transient immunity. |
| GND (Pin 4) | Ground Reference | Primary return path for reference output and internal circuitry; must connect to clean analog ground plane. |
| OUT (Pin 6) | Precision Output | Delivers regulated 5.000V; stable with ≥1µF capacitive loads but requires no external capacitor for stability. |
| Pins 1,3,5,7,8 | No Connection | Not bonded or connected internally; must remain unconnected on PCB to avoid parasitic coupling or ESD paths. |
Key Features
| Feature | Design Value |
|---|---|
| Laser-trimmed thin-film resistors | Enable ±2mV initial accuracy and 5ppm/°C tempco without post-package trimming. |
| Proprietary curvature-correction | Compensates second-order thermal effects in bandgap core, achieving flat output vs. temperature. |
| No external compensation capacitor | Reduces BOM count and board area by eliminating mandatory stability capacitor required by most series references. |
| Supply-current independence | Quiescent current varies ≤8µA/V across full input range-critical for consistent battery-life estimation in wide-input systems. |
| Stable with 1µF capacitive loads | Supports direct driving of ADC reference inputs and op-amp bias networks without isolation resistors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADR4550BRZ | 5.0V output, ±1mV initial accuracy, 3ppm/°C max tempco, 950µA quiescent current, SO-8 package | Higher accuracy and lower drift, but 9.5× higher supply current limits battery life in portable systems | Select ADR4550BRZ when ultimate stability outweighs power budget constraints; MAX6165AESA+ preferred for micropower designs. |
| REF5050AIDR | 5.0V output, ±0.5mV initial accuracy, 3ppm/°C max tempco, 1mA quiescent current, SO-8 package | Superior initial tolerance and drift spec, but 10× higher IQ and requires 1µF output capacitor for stability | Choose REF5050AIDR for lab-grade instrumentation where power is secondary; MAX6165AESA+ fits size- and current-sensitive embedded systems. |
Compared with ADR4550BRZ and REF5050AIDR, MAX6165AESA+ trades minor accuracy and drift margin for decisive advantages in quiescent current (100µA vs. >950µA), zero-external-capacitor operation, and dropout voltage-making it uniquely suited for compact, battery-constrained 5V reference applications.

FAQ
What is the guaranteed initial accuracy of the MAX6165AESA+ at +25°C?
The MAX6165AESA+ guarantees ±2mV initial output voltage accuracy at +25°C, corresponding to a 5.000V nominal output ranging from 4.998V to 5.002V. This specification is 100% production tested and applies across the full -40°C to +85°C operating temperature range per design guarantee.
Does the MAX6165AESA+ require an external output capacitor for stability?
No, the MAX6165AESA+ does not require an external output capacitor for stability due to internal compensation. It remains stable with capacitive loads up to 1µF, but adding ≥0.1µF improves transient response during load steps. The absence of a mandatory capacitor saves board area in space-critical designs.
What is the minimum input voltage required for proper operation of the MAX6165AESA+?
The MAX6165AESA+ requires a minimum input voltage of VOUT + 0.2V = 5.2V at 1mA load, per the dropout specification. Its absolute maximum input is 12.6V. Operation below 5.2V may cause output regulation loss or increased drift; the device is not functional at VIN < 5.2V under load.
How does the supply current of the MAX6165AESA+ vary with input voltage?
The MAX6165AESA+ exhibits ≤8µA/V variation in quiescent supply current across its input range (5.2V to 12.6V), with typical IQ = 100µA and max = 120µA. This near-constant current simplifies power budgeting and ensures predictable battery drain regardless of input rail fluctuations.
Can the MAX6165AESA+ sink load current, and if so, what is its rated capability?
Yes, the MAX6165AESA+ can sink up to 2mA of load current with a specified compliance of 2.4–8.0mV/mA load regulation. Sinking operation is valid when the output is pulled below its regulated voltage-for example, in active bias networks or certain DAC reference configurations-within absolute maximum ratings.
