REF195GS

Overview

The REF195GS is a precision micropower, low dropout voltage reference from the Analog Devices REF19x series. It provides a fixed 5 V output with an initial accuracy of ±2 mV maximum and a temperature coefficient of 5 ppm/°C maximum. The device operates on a supply voltage ranging from 5.1 V to 15 V, consuming a maximum supply current of 45 μA. It features a high output current capability of 30 mA and includes short-circuit protection. The component is housed in an 8-lead SOIC package and supports a sleep mode that reduces supply current to 15 μA.

Feature Summary

Utilizes patented temperature drift curvature correction circuitry and laser trimming for high stability.
Operates with low dropout voltage, requiring minimal headroom above the output voltage.
Includes a dedicated SLEEP pin to disable the output and minimize power consumption.
Features integrated short-circuit protection for enhanced reliability.

Applications

Portable instrumentation
Analog-to-digital (ADC) and digital-to-analog (DAC) converters
Smart sensors
Solar powered applications
Loop-current-powered instruments

Procurement Notes

Verify the specific electrical grade (E, F, or G) required for your application, as performance specifications vary by grade. Confirm the package suffix matches the desired footprint, such as GS for SOIC. Check for any product change notifications or obsolescence notices prior to finalizing design-in decisions.

Selection Notes

Select the REF195GS when a stable 5 V reference is needed with strict limits on quiescent current and temperature drift. Ensure the supply voltage remains within the specified range to maintain regulation. Consider the thermal resistance and power dissipation if operating at higher load currents or elevated temperatures.

Part Context

The REF195GS belongs to the REF19x series of precision band gap voltage references. This family offers various nominal output voltages and packaging options, including SOIC, TSSOP, and PDIP. The series is designed for applications requiring high accuracy and low power consumption across industrial temperature ranges.
