MAX6195AESA

Overview

The MAX6195AESA+ is a precision, micropower, low-dropout voltage reference providing a fixed 5.0V output in an 8-pin SO package. It features a maximum initial accuracy of ±2mV and a temperature coefficient of less than 5ppm/°C. The device draws a maximum quiescent supply current of 35µA and supports source and sink currents up to 500µA with a dropout voltage of approximately 100mV at full load. Operating over a -40°C to +85°C range, it maintains stability with capacitive loads up to 2.2nF.

Feature Summary

• Proprietary curvature-correction circuit combined with laser-trimmed thin-film resistors ensures high initial accuracy and very low temperature drift.
• Series-mode architecture delivers virtually constant supply current independent of input voltage variations, maximizing efficiency for battery-powered applications.
• Internally compensated design allows stable operation with capacitive loads up to 2.2nF without requiring external compensation components.

Applications

• Hand-Held Instruments
• Analog-to-Digital and Digital-to-Analog Converters
• Industrial Process Control
• Precision 3V/5V Systems
• Hard-Disk Drives

Procurement Notes

Verify the specific suffix 'A' indicates the ±2mV initial accuracy grade and 'ESA+' denotes the lead-free RoHS-compliant 8-SO package. Confirm the operating temperature range matches the -40°C to +85°C specification. Ensure the input voltage source can provide transient currents during turn-on if operating near minimum dropout conditions.

Selection Notes

Select this component when a fixed 5.0V reference with high precision is required in space-constrained designs. The low quiescent current makes it suitable for battery-operated systems where power efficiency is critical. Verify that the application load does not exceed the 500µA sourcing or sinking capability to maintain specified regulation performance.

Part Context

This part belongs to the MAX6190–MAX6195/MAX6198 family of precision bandgap references manufactured by Analog Devices / Maxim Integrated. The family shares common internal architectures and packaging options but varies in output voltage and accuracy grades. The MAX6195 specifically provides the 5.0V output option within this series.

Replacement Considerations

Other members of the MAX619x family (e.g., MAX6190 through MAX6194, MAX6198) share identical pinouts and packages but offer different fixed output voltages. Substitution requires matching the required output voltage level while maintaining the same accuracy grade and package type.

FAQ

Does the MAX6195 require an external capacitor for stability?

No, the device is internally compensated and stable with capacitive loads ranging from 0 to 2.2nF. An external capacitor is optional and primarily used to reduce overshoot during load transients.

What is the maximum load current the MAX6195 can handle?

The device guarantees load-regulation specifications for source and sink currents up to 500µA.
