Diodes ZXRE330 voltage reference

The ZXRE330 3.3 V shunt voltage reference from Diodes has been introduced to help achieve improvements in both stability and power consumption. Pin-compatible with industry-standard parts, the product is offered in surface-mount SOT23 and through-hole TO92 package options.

With a typical temperature coefficient as low as 20 ppm/°C, the precision micropower device provides stable performance across an industrial operating temperature range of -40 to +85°C. Output voltage tolerance is tight at ±2% at +25°C for the ZXRE330E and ±0.5% at +25°C for the ZXRE330A.The product’s low-power performance is a result of its low knee current, 1 µA typical, with good performance maintained over the device’s full operating current range of 2 µA to 5 mA.

The reference has been designed to be tolerant of capacitive loads and requires no output capacitor. Its low-output noise performance of 55 µV_RMS ensures a clean output from 10 Hz to 10 kHz.
