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.

簡介

MCP1501屬于集成電路（IC）的電壓基準。由制造生產(chǎn)的MCP1501電壓基準產(chǎn)品屬于基準電壓源系列，可通過相對較不穩(wěn)定的電源提供穩(wěn)定的電勢，電壓值始終保持恒定，以便在測量、控制和類似應用中用作比較的標準。其功能行為可能與用于大功率調(diào)節(jié)的線性穩(wěn)壓器相似，但基準電壓源器件卻不適合用于此類用途。用作比較標準時，若輸出電流容量或?qū)嶋H負載電流增大，其性能通常會降低。
