REF3225集成电路（IC）的电压基准规格书PDF中文资料

REF3225属于集成电路（IC）的电压基准。由德州仪器制造生产的REF3225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。

DESCRIPTION

The REF32xx is a very low drift, micropower,

low-dropout, precision voltage reference family

available in the tiny SOT23-6 package.

The small size and low power consumption (120μA

max) of the REF32xx make it ideal for portable and

battery-powered applications. This reference is stable

with any capacitive load.

The REF32xx can be operated from a supply as low

as 5mV above the output voltage, under no load

conditions. All models are specified for the wide

temperature range of –40°C to +125°C.
