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.

簡介

LM4041B屬于集成電路（IC）的電壓基準(zhǔn)。由制造生產(chǎn)的LM4041B電壓基準(zhǔn)產(chǎn)品屬于基準(zhǔn)電壓源系列，可通過相對(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。
