描述 Description

The ZRT040 is a monolithic integrated circuit providing a
precise stable reference voltage of 4.01V at 500μA.

The circuit features a knee current of 150μA and operation
over a wide range of temperatures and currents.

The ZRT040 is available in a SOT223 package for surface
mount applications. This device offers a trim facility whereby
the output voltage can be adjusted as shown in the
schematic diagram. This facility is used when compensating
for system errors or setting the reference output to a
particular value. When the trim facility is not used, the pin
should be left open circuit.

简介

ZRT040属于集成电路（IC）的电压基准。由制造生产的ZRT040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。
