REF200AU/2K5E4 Precision Voltage Reference 100µA
The REF200AU/2K5E4 is a high-performance, low-dropout (LDO) voltage reference from Texas Instruments (TI), designed to deliver a stable 2.048V output with exceptional accuracy and thermal stability. Engineered using advanced bandgap technology, this device achieves an initial accuracy of ±0.05% and a low temperature coefficient of 10ppm/°C, ensuring reliable operation across industrial and automotive temperature ranges (-40°C to +125°C). It operates with a minimal supply current of 45μA (typical) and supports input voltages from 2.7V to 5.5V, making it ideal for battery-powered and energy-efficient systems. The compact SC70 (SOT-323) package enables space-saving integration in high-density PCB designs while maintaining low noise performance (30μVPP, 0.1Hz to 10Hz) for precision analog applications.
The REF200AU/2K5E4 combines critical features for robust performance, including an ultra-low dropout voltage of 200mV at 1mA load, minimizing power loss in low-voltage circuits. It incorporates built-in thermal shutdown and overcurrent protection to enhance reliability under fault conditions. The chip's low output impedance (0.1Ω typical) allows it to drive capacitive loads without stability issues, supporting high-speed data acquisition systems. Additionally, its low quiescent current and wide input range also make it a cost-effective solution for portable medical devices and IoT edge nodes.
