描述 Description

The ZXRE1004 is a 1.22 volt bandgap reference circuit designed for ultra low current operation, typically 4µA.
The device is available in a SOT23 surface mount package offering the ultimate in space and power saving. These features make the ZXRE1004 particularly suitable for portable and battery powered applications. SOT23 tolerance selection is available to 0.5% for precision applications. Excellent performance is maintained over the 8µA to 20mA operating current range with a typical temperature coefficient of only 20ppm/°C. The device has been designed to be highly tolerant of capacitive loads so maintaining excellent stability.
As well as the SOT23, the ZXRE1004 can offer a pin for pin compatible alternative to the REF1004, LT1004 and LM185/385 series of voltage references with an E-Line (TO92 style) equivalent.

简介

ZXRE1004属于集成电路（IC）的电压基准。由制造生产的ZXRE1004电压基准产品属于基准电压源系列，可通过相对较不稳定的电源提供稳定的电势，电压值始终保持恒定，以便在测量、控制和类似应用中用作比较的标准。其功能行为可能与用于大功率调节的线性稳压器相似，但基准电压源器件却不适合用于此类用途。用作比较标准时，若输出电流容量或实际负载电流增大，其性能通常会降低。
