LM336-2.5屬于集成電路（IC）的電壓基準(zhǔn)。由美國(guó)德州儀器公司制造生產(chǎn)的LM336-2.5電壓基準(zhǔn)產(chǎn)品屬于基準(zhǔn)電壓源系列，可通過(guò)相對(duì)較不穩(wěn)定的電源提供穩(wěn)定的電勢(shì)，電壓值始終保持恒定，以便在測(cè)量、控制和類似應(yīng)用中用作比較的標(biāo)準(zhǔn)。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(zhǔn)電壓源器件卻不適合用于此類用途。用作比較標(biāo)準(zhǔn)時(shí)，若輸出電流容量或?qū)嶋H負(fù)載電流增大，其性能通常會(huì)降低。

description/ordering information

The LM236-2.5, LM336-2.5, and LM336B-2.5

integrated circuits are precision 2.5-V shunt

regulator diodes. These reference circuits

operate as low-temperature-coefficient 2.5-V

Zener diodes with a 0.2-Ω dynamic impedance. A

third terminal provided on the circuit allows the

reference voltage and temperature coefficient to

be trimmed easily.

The series is useful as precision 2.5-V low-voltage references (VZ) for digital voltmeters, power supplies, or

operational-amplifier circuitry. The 2.5-V voltage reference makes it convenient to obtain a stable reference from

5-V logic supplies. Devices in this series operate as shunt regulators, and can be used as either positive or

negative voltage references.

The LM236-2.5 is characterized for operation from ?25°C to 85°C. The LM336-2.5 and LM336B-2.5 are

characterized for operation from 0°C to 70°C.
