Product details
Overview
MAX6195BESA+T from Maxim Integrated is a precision, micropower, low-dropout series-mode bandgap voltage reference delivering 5.000V output with ±2mV initial accuracy, 5ppm/°C max temperature coefficient, and 35µA max quiescent supply current. It operates from (VOUT + 0.2V) to 12.6V input, supports ±500µA load sourcing/sinking, and is used in high-accuracy ADC/DAC biasing and portable instrumentation.
For engineers reviewing the MAX6195BESA+T datasheet, MAX6195BESA+T pinout, MAX6195BESA+T application, or MAX6195BESA+T equivalent, key selection criteria include guaranteed 100mV dropout at 500µA, 0.17µV/µA load regulation, 25µV/V line regulation, stability with up to 2.2nF capacitive load, and SO-8 package compatibility for space-constrained precision analog designs.
Technical Context
This device uses a proprietary curvature-correction circuit and laser-trimmed thin-film resistors to achieve <5ppm/°C temperature coefficient and ±2mV initial accuracy across –40°C to +85°C. Its series-mode architecture enables bidirectional 500µA load current capability without external components.
Internally compensated for fast settling (220µs to 0.1%), it maintains stability with capacitive loads from 0 to 2.2nF and exhibits minimal supply current variation (0.8µA/V) over input voltage - critical for battery-powered systems requiring long-term voltage reference integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.000V ±2mV (guaranteed initial accuracy enables direct use in 16-bit ADC references without trimming) |
| Temp Coefficient | ≤5ppm/°C (ensures ≤±0.25mV drift over –40°C to +85°C for industrial-grade stability) |
| Quiescent Current | ≤35µA (supports >10-year battery life in 10µA-sleep IoT sensor nodes) |
| Dropout Voltage | 100mV at 500µA load (enables operation from 5.1V supply in 5V systems with margin) |
| Load Regulation | 0.17µV/µA (maintains <85µV shift across full ±500µA load range) |
| Line Regulation | 25µV/V (limits output change to <250µV over 10V input swing) |
| Noise (0.1–10Hz) | 240µVP-P (low-frequency noise compatible with precision weigh-scale front-ends) |
Pinout & Package
MAX6195BESA+T is housed in an 8-pin SO (Small Outline) package with exposed pad (RoHS-compliant, lead-free). Pin 1 is OUT; Pin 2 is IN; Pin 4 is GND; Pins 1,3,5,7,8 are No Connect (N.C.).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 7, 8 | N.C. | No internal connection - floating; no routing or grounding required |
| 2 | IN | Positive supply input; must exceed VOUT + 0.2V for regulation (min 5.2V for 5V output) |
| 4 | GND | Analog ground reference; requires low-impedance connection to system AGND plane |
| 6 | OUT | Stable 5.000V reference output; capable of sourcing or sinking up to 500µA |
Key Features
| Feature | Design Value |
|---|---|
| Initial Accuracy | ±2mV (eliminates factory calibration in portable multimeters and handheld DMMs) |
| Capacitive-Load Stability | 0–2.2nF (enables direct connection to ADC input caps without oscillation risk) |
| Turn-On Settling Time | 220µs to 0.1% (supports fast wake-up in duty-cycled data loggers) |
| Bidirectional Load Drive | ±500µA (allows single reference to bias both high-side and low-side signal chains) |

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 | 5.000V, ±1.5mV initial accuracy, 3ppm/°C TC, 950µA supply current | Higher power consumption; requires external decoupling for 2.2nF stability | Select when ultra-low TC (<3ppm/°C) outweighs micropower requirement |
| REF5050AIDR | 5.000V, ±1mV initial accuracy, 3ppm/°C TC, 1.1mA supply current, 100µVpp noise | Lower noise but 31× higher supply current; not suitable for battery operation | Select for low-noise, high-precision lab equipment where power is unconstrained |
Compared with ADR4550BRZ and REF5050AIDR, MAX6195BESA+T uniquely balances ±2mV accuracy, 5ppm/°C TC, and 35µA supply current in SO-8 - making it optimal for portable, long-life, medium-precision applications where thermal drift and battery runtime are co-constrained.

FAQ
What is the maximum load current supported by MAX6195BESA+T?
MAX6195BESA+T supports bidirectional load current up to ±500µA - meaning it can source up to 500µA to a load or sink up to 500µA from a load while maintaining regulation. This capability is guaranteed across the full –40°C to +85°C temperature range and is validated with 100mV dropout at 500µA, ensuring reliable operation in precision biasing circuits.
Does MAX6195BESA+T require an output capacitor for stability?
No, MAX6195BESA+T is internally compensated and stable with capacitive loads from 0 to 2.2nF - including no external capacitor. While adding a capacitor (e.g., 100pF–1nF) improves transient response to load steps, it is optional and not required for basic DC stability, making MAX6195BESA+T ideal for space-constrained PCB layouts where board area is at a premium.
What is the minimum input voltage required for regulation with MAX6195BESA+T?
The minimum input voltage for regulation is VOUT + 0.2V = 5.2V. This is specified as the lower bound of the supply voltage range (VIN ≥ VOUT + 0.2V), and dropout is guaranteed at 100mV when sourcing 500µA. Operating below 5.2V risks loss of regulation and increased output error, especially under load or at temperature extremes.
How does the supply current of MAX6195BESA+T vary with input voltage?
MAX6195BESA+T exhibits exceptional supply voltage immunity: quiescent current varies by only 0.8µA per volt across its input range (VOUT + 0.2V to 12.6V). At 5.2V input, IIN is typically 27–35µA; at 12.6V, it increases by ≤6µA. This near-constant current minimizes error coupling in unregulated supplies and simplifies power budgeting in multi-rail systems.
Is MAX6195BESA+T RoHS-compliant and lead-free?
Yes, MAX6195BESA+T is RoHS-compliant and lead-free, indicated by the "+" suffix in the part number per Maxim's ordering nomenclature. It meets JEDEC J-STD-020 moisture sensitivity level (MSL) requirements for SO-8 packages and is qualified for reflow soldering at +260°C peak temperature, supporting standard automated assembly processes.
