V62/18622-03XE

Overview

The V62/18622-03XE is a low-drift, low-power series voltage reference from Texas Instruments. It provides a fixed 3V output with ±0.05% initial accuracy and 10 ppm/°C temperature drift. The device operates within an input voltage range of up to 13V and delivers 10mA load current. Key electrical characteristics include 3.8 µVp-p/V output noise and less than 95µA quiescent current. It functions across a temperature range of -55°C to +150°C in a compact SOT-23-6 package.

Feature Summary
