The Diodes Incorporated ZXRE330ASA-7 is a precision 3.3V micropower shunt voltage reference designed for battery-powered equipment, precision power supplies, portable instrumentation, data acquisition systems, and low-current voltage-clamp applications. Its low knee current and stable reference characteristics make it well suited for low-power analog and mixed-signal designs.
The ZXRE330ASA-7 is the A accuracy grade, providing a nominal 3.3V reference voltage with ±0.5% tolerance at 25°C and IR = 100µA. The recommended reverse operating current range is 2µA to 5mA, while typical minimum operating current is approximately 1µA.
The device offers a typical 2Ω dynamic output impedance at IR = 2mA and 120Hz, along with typical output noise of 55µVRMS from 10Hz to 10kHz at IR = 100µA. Typical temperature coefficient is approximately 20ppm/°C, and the device is designed for stable operation with capacitive loads without requiring an output capacitor.
The ZXRE330ASA-7 is supplied in a compact SOT-23 surface-mount package with maximum power dissipation of 300mW at 25°C. Its recommended ambient operating temperature range is -40°C to +85°C. The -7 orderable version is listed as Production and is supplied on tape and reel with 3,000 units per reel; its package identification code is DC.
