Overview
The REF3025AIDBZRG4, produced by Texas Instruments, is part of the REF30xx family of precision, low-power, low-dropout voltage references. This component is packaged in a tiny 3-pin SOT-23 package, making it highly suitable for applications where space is limited. The REF3025 offers excellent temperature drift and initial accuracy, operating at a quiescent current of 42 µA (typical). This makes it very attractive for loop-powered industrial applications and other scenarios requiring high precision and low power consumption.
