Product details
Overview
MAX6195AESA from Maxim Integrated is a precision, micropower, low-dropout series voltage reference delivering 5.000V output with ±2mV initial accuracy, 5ppm/°C max temperature coefficient, and 35µA max quiescent current. It operates from (VOUT + 0.2V) to 12.6V input, supports ±500µA load current, and is used in high-accuracy ADC/DAC biasing and portable instrumentation power rails.
For engineers reviewing the MAX6195AESA datasheet, MAX6195AESA pinout, MAX6195AESA application, or MAX6195AESA equivalent, key selection criteria include guaranteed 5.000V output tolerance, sub-5ppm/°C drift over -40°C to +85°C, dropout voltage ≤100mV at 500µA, stability with up to 2.2nF capacitive load, and SO-8 package compatibility for space-constrained analog signal chains.
Technical Context
This device is a series-mode bandgap voltage reference employing proprietary curvature-correction circuitry and laser-trimmed thin-film resistors to achieve high initial accuracy and ultra-low thermal drift. Its internal compensation ensures fast 220µs turn-on settling to 0.1% and stable operation without external compensation.
It functions as a two-terminal active reference: IN supplies regulated current to the internal bandgap core, while OUT delivers a precise, low-noise 5.000V reference voltage capable of sourcing or sinking up to 500µA. Load regulation is specified at 0.17µV/µA and line regulation at 25µV/V, enabling use in precision data acquisition systems where supply and load variations must not perturb reference integrity.
Key Specifications

FAQ
What is the guaranteed initial accuracy of MAX6195AESA over temperature?
The MAX6195AESA guarantees ±2mV initial output voltage accuracy across its full operating temperature range of -40°C to +85°C. This specification is tested and binned during production, ensuring that every unit delivers 5.000V within ±2mV at +25°C and maintains that tolerance across temperature extremes without calibration.
Does MAX6195AESA require an external output capacitor for stability?
No, MAX6195AESA is internally compensated and stable with output capacitance ranging from 0 to 2.2nF. An external capacitor is optional and only recommended in applications subject to rapid load or supply transients to improve transient response-no minimum capacitor is required for basic DC stability.
What is the maximum load current MAX6195AESA can source or sink?
MAX6195AESA is specified to source and sink up to ±500µA while maintaining guaranteed load regulation (0.17µV/µA) and output voltage accuracy. Exceeding ±500µA may cause increased dropout voltage or deviation beyond the published 5.000V ±2mV tolerance.
What is the minimum input voltage required for MAX6195AESA to regulate at full load?
The minimum input voltage for MAX6195AESA is VOUT + 0.2V = 5.2V under full 500µA load conditions. At light or no load, regulation is maintained down to 5.0V, but the 100mV dropout specification applies at 500µA-so 5.2V ensures guaranteed performance across the full load range.
Is MAX6195AESA compatible with standard SO-8 footprints and reflow profiles?
Yes, MAX6195AESA uses a standard 8-pin SO package (outline 21-0041) with RoHS-compliant lead finish. It is qualified for standard Pb-free reflow soldering per JEDEC J-STD-020, with peak temperature up to +260°C, and fits industry-standard SO-8 land patterns (land pattern 90-0096).
