LM4041B数据手册集成电路（IC）的电压基准规格书PDF

描述 Description

The LM4041 is a precision two-terminal shunt mode,bandgap voltage reference with a fixed reverse breakdownvoltage of 1.225V. Ideal for space-critical applications,the LM4041 is offered in the subminiature 3-pinSC70 surface-mount package (1.8mm x 1.8mm), 50%smaller than comparable devices in SOT23 surfacemountpackages (SOT23 versions are also available).
Laser-trimmed resistors ensure precise initial accuracy.With a 100ppm/°C temperature coefficient, the deviceis offered in four grades of initial accuracy ranging from0.1% to 1%. The LM4041 has a 60µA to 12mA shuntcurrent capability with low dynamic impedance, ensuringstable reverse-breakdown voltage accuracy over awide range of operating temperatures and currents.
The LM4041 does not require an external stabilizingcapacitor while ensuring stability with any capacitiveload.
The LM4041 is guaranteed over the temperature range-40°C to +125°C.

简介

LM4041B属于集成电路（IC）的电压基准。由制造生产的LM4041B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。
