TLV70732DQNT集成電路（IC）的線性+開關穩(wěn)壓器規(guī)格書PDF中文資料

TLV70732DQNT屬于集成電路（IC）的線性+開關穩(wěn)壓器。由德州儀器制造生產(chǎn)的TLV70732DQNT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換為熱量。對于大多數(shù)應用而言，雖然這種穩(wěn)壓器的效率低于開關模式的穩(wěn)壓器，但它們通常更適合對噪聲高度敏感的應用。

3 Description

The TLV707 series (TLV707 and TLV707P) of lowdropout

linear regulators (LDOs) are low quiescent

current devices with excellent line and load transient

performance for power-sensitive applications. These

devices provide a typical accuracy of 0.5. All

versions have thermal shutdown and overcurrent

protection for safety.

Furthermore, these devices are stable with an

effective output capacitance of only 0.1 μF. This

feature enables the use of cost-effective capacitors

that have higher bias voltages and temperature

derating. These devices also regulate to the specified

accuracy with no output load.

The TLV707P also provides an active pulldown circuit

to quickly discharge the outputs.

The TLV707 series of LDOs are available in a 1-mm

× 1-mm DQN (X2SON) package that makes them

desirable for handheld applications.
