TLV7031集成電路（IC）的線性+開關(guān)穩(wěn)壓器規(guī)格書PDF中文資料

TLV7031屬于集成電路（IC）的線性+開關(guān)穩(wěn)壓器。由德州儀器制造生產(chǎn)的TLV7031穩(wěn)壓器 - 線性線性穩(wěn)壓器用于提供穩(wěn)定的輸出電壓，無論負載電流、輸入電壓或環(huán)境因素如何變化，這些輸出電壓通常都要保持不變。它們的工作原理要求輸入電壓維持在高于所需的輸出電壓，而且要超出某個最小量，并且在工作時會將輸入端的任何多余電壓轉(zhuǎn)換為熱量。對于大多數(shù)應(yīng)用而言，雖然這種穩(wěn)壓器的效率低于開關(guān)模式的穩(wěn)壓器，但它們通常更適合對噪聲高度敏感的應(yīng)用。

3 Description

The TLV703x-Q1/TLV704x-Q1 are low-voltage,

nanopower comparators with rail-to-rail inputs. These

comparators are applicable for space-critical and

power conscious designs like infotainment, telematics,

and head unit applications.

The TLV703x-Q1 and TLV704x-Q1 offer an excellent

combination of power and speed. The benefit of

fast response time at nanopower enables powerconscious

systems to monitor and respond quickly to

fault conditions. With an operating voltage range of

1.6 V to 6.5 V, these comparators are compatible with

1.8 V, 3 V, and 5 V systems.

The TLV703x-Q1 and TLV704x-Q1 also ensure no

output phase inversion with overdriven inputs and

internal hysteresis, so engineers can use this family of

comparators for precision voltage monitoring in harsh,

noisy environments where slow-moving input signals

must be converted into clean digital outputs.

The TLV703x-Q1 have a push-pull output stage

capable of sinking and sourcing milliamps of current.

The TLV704x-Q1 have an open-drain output stage

that can be pulled beyond VCC.
