REF200AU/2K5 Precision Dual Current Source & Sink Regulator 100µA 8-SOIC
The REF200AU/2K5, manufactured by Texas Instruments, is a high-precision, low-power dual current source and sink designed for demanding analog circuit applications. Delivering a fixed 100μA current with ±0.25% initial accuracy, it operates from a wide 2.5V to 40V supply range, integrating two independent, temperature-stabilized current sources in a compact SOIC-8 package. This device provides exceptional stability, low noise, and robust performance for precision current biasing, sensor excitation, and voltage reference circuits across industrial, medical, and communication systems.
This component boasts high precision with excellent temperature stability, featuring a low temperature coefficient of ±25ppm/°C and operating reliably from -25°C to +85°C. It offers a fixed 100μA current output with ±0.25% initial accuracy, low noise performance, and a low operating current of 100μA, making it ideal for battery-powered and low-energy applications. The device includes built-in short-circuit protection and thermal shutdown mechanisms to enhance system reliability, while its SOIC-8 package (4.90mm x 3.90mm) facilitates easy PCB layout and space optimization. It is fully RoHS-compliant, supports surface-mount technology (SMT), and comes in tape-and-reel packaging (2500 units) for high-volume production.
