MCP1501数据手册集成电路（IC）的电压基准规格书PDF

描述 Description

The MCP1501 is a high-precision buffered voltage reference with an initial accuracy of 0.10% and is available in 10 voltage options. The MCP1501 is a low-drift bandgap-based reference and uses chopper-based amplifiers which significantly reduces the drift and provides high current output. The MCP1501 is available in a very small 2x2 WDFN package, as well as the SOT-23 and SOIC packages. SOT-23 package is AEC-Q100 automotive qualified.

简介

MCP1501属于集成电路（IC）的电压基准。由制造生产的MCP1501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。
