LM4040B25QFTA集成电路（IC）的电压基准规格书PDF中文资料

LM4040B25QFTA属于集成电路（IC）的电压基准。由美台半导体制造生产的LM4040B25QFTA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。

描述 Description

The LM4040Q is a family of bandgap circuits designed to achieve precision micro-power voltage references of 2.5V, 3.0V and 5.0V. The devices are available in 0.2 B-grade, 0.5 C-grade and 1 D-grade initial tolerances.

They are available in small outline SOT23 surface mount package which is ideal for applications where space is at a premium. Excellent performance is maintained over the 60µA to 15mA operating current range with a typical temperature coefficient of only 20ppm/°C. The device has been designed to be highly tolerant of capacitive loads therefore maintaining excellent stability.
