ISL21007CFB830Z

Overview

The ISL21007CFB830Z is a precision series voltage reference IC manufactured by Renesas Electronics Corporation, formerly Intersil. It provides a fixed 3V output with an initial accuracy of ±0.08%. The device operates within an input voltage range of 3.2V to 5.5V and delivers a maximum output current of 7 mA while consuming only 150 µA of supply current. It features a low temperature coefficient of 5 ppm/°C and exhibits low noise characteristics of 4.5 µVp-p from 0.1Hz to 10Hz. Packaged in an 8-SOIC surface-mount case, it supports an operating temperature range of -40°C to +125°C.
