REF3030TB-GT3

Overview

The REF3030TB-GT3 is a high-precision, low-drift CMOS voltage reference from the REF30xx family manufactured by onsemi. It provides a fixed nominal output voltage of 3.0 V with an accuracy of ±0.2%. The device operates within a supply voltage range of 2.7 V to 5.5 V and supports a maximum temperature drift of 50 ppm/°C across the -40°C to +85°C operating range. It can source or sink up to 10 mA of load current while maintaining a maximum quiescent current of 30 µA.

Feature Summary

Provides stable voltage regulation with a maximum temperature drift of 50 ppm/°C over the specified operating range.
Capable of sourcing or sinking up to 10 mA of load current for versatile interface requirements.
Designed to operate without an output bypass capacitor in most applications, simplifying circuit design.
Manufactured using CMOS technology to ensure low quiescent current consumption.

Applications

Battery powered systems
A/D and D/A converters
Precision regulator systems
Portable medical equipment

Procurement Notes

Verify the specific suffix 'GT3' corresponds to the Tape & Reel shipping configuration as documented in the ordering information table. Confirm that the component meets RoHS compliance standards and is lead-free. Ensure the input supply voltage remains within the 2.7 V to 5.5 V operational limits during integration to maintain specified electrical characteristics.

Selection Notes

Select this component when a fixed 3.0 V reference with ±0.2% initial accuracy is required. It is suitable for designs needing bidirectional current capability (sourcing/sinking) up to 10 mA. Consider the SOT-23 package for space-constrained layouts. Verify that the 50 ppm/°C drift specification meets the thermal stability requirements of the target application environment.

Part Context

This part belongs to the REF30xx series of high precision voltage references. The family includes variants with outputs ranging from 1.25 V to 4.096 V. All members share the same SOT-23 3-lead package and core CMOS architecture, differing primarily in their internal resistor networks to set the specific output voltage level.

Replacement Considerations

Other devices within the REF30xx family, such as REF3025TB-GT3 or REF3033TB-GT3, offer identical performance characteristics with different fixed output voltages. Cross-referencing pinouts and package dimensions is recommended when substituting with other voltage levels from the same manufacturer.

FAQ

Does the REF3030TB-GT3 require an output bypass capacitor?

In most applications, the device does not require an output bypass capacitor. However, capacitive loads can affect Power Supply Rejection Ratio (PSRR) and output impedance.
