ADR435ARZ

ADR435ARZ Description

The ADR435ARZ from Analog Devices Inc. is a high-precision 5V series voltage reference from the XFET® family, designed for applications demanding ultra-stable voltage regulation. Housed in an 8-pin SOIC package, this surface-mount (SMD) device offers an exceptional ±0.12% initial accuracy and a low 10ppm/°C temperature coefficient, ensuring minimal drift across operating conditions. With a 7V to 18V input range, it delivers a fixed 5V output while consuming only 800µA supply current, making it ideal for power-sensitive designs. The 30mA output current capability supports direct load driving, and its ROHS3 compliance and REACH-unaffected status align with modern environmental standards.
