LM336Z-2.5/LFT1集成电路（IC）的电压基准规格书PDF中文资料

LM336Z-2.5/LFT1属于集成电路（IC）的电压基准。由德州仪器制造生产的LM336Z-2.5/LFT1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 LM136-2.5-N/LM236-2.5-N and LM336-2.5-N

integrated circuits are precision 2.5V shunt regulator

diodes. These monolithic IC voltage references

operate as a low-temperature-coefficient 2.5V zener

with 0.2Ω dynamic impedance. A third terminal on the

LM136-2.5-N allows the reference voltage and

temperature coefficient to be trimmed easily.

The LM136-2.5-N series is useful as a precision 2.5V

low voltage reference for digital voltmeters, power

supplies or op amp circuitry. The 2.5V make it

convenient to obtain a stable reference from 5V logic

supplies. Further, since the LM136-2.5-N operates as

a shunt regulator, it can be used as either a positive

or negative voltage reference.

The LM136-2.5-N is rated for operation over −55°C to

+125°C while the LM236-2.5-N is rated over a −25°C

to +85°C temperature range.

The LM336-2.5-N is rated for operation over a 0°C to

+70°C temperature range. See the connection

diagrams for available packages.
