Diodes Incorporated introduced the ZXRE330. This 3.3V shunt voltage reference helps achieve improvements in both stability and power consumption for portable instrumentation and battery-powered equipment such as notebook computers. Pin-compatible with industry-standard parts, the ZXRE330 is offered in surface-mount SOT23 and through-hole TO92 package options.
With a typical temperature coefficient as low as 20ppm/oC, this precision micropower device provides highly stable performance across an industrial operating temperature range of -40oC to +85oC. Output voltage tolerance is tight: ±2% at +25oC for the ZXRE330E and ±0.5% at +25oC for the ZXRE330A.
The ZXRE330’s low power performance is a result of its very low knee current of 1μA typical with excellent performance maintained over the device’s full operating current range of 2μA to 5mA.
The ZXRE330 reference has also been designed to be highly tolerant of capacitive loads and requires no output capacitor. In addition, its low output noise performance of 55μVRMS ensures a clean output from 10Hz to 10kHz.
