TL431IDBVRE4規(guī)格書詳情
TL431IDBVRE4屬于集成電路（IC）的電壓基準(zhǔn)。由德州儀器制造生產(chǎn)的TL431IDBVRE4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，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。

3 Description
The TL431LI / TL432LI are pin-to-pin alternatives
to TL431 / TL432. TL43xLI offers better stability,
lower temperature drift (VI(dev)), and lower
reference current (Iref) for improved system
accuracy.
The TL431 and TL432 devices are three-terminal
adjustable shunt regulators, with specified thermal
stability over applicable automotive, commercial, and
military temperature ranges. The output voltage can
be set to any value between Vref (approximately
2.5 V) and 36 V, with two external resistors.
These devices have a typical output impedance
of 0.2 Ω. Active output circuitry provides a very
sharp turn-on characteristic, making these devices
excellent replacements for Zener diodes in many
applications, such as onboard regulation, adjustable
power supplies, and switching power supplies. The
TL432 device has exactly the same functionality and
electrical specifications as the TL431 device, but has
different pinouts for the DBV, DBZ, and PK packages.
Both the TL431 and TL432 devices are offered in
three grades, with initial tolerances (at 25°C) of
0.5, 1, and 2, for the B, A, and standard
grade, respectively. In addition, low output drift versus
temperature ensures good stability over the entire
temperature range.
The TL43xxC devices are characterized for operation
from 0°C to 70°C, the TL43xxI devices are
characterized for operation from –40°C to 85°C, and
the TL43xxQ devices are characterized for operation
from –40°C to 125°C.
