L5150GJ集成電路（IC）的線性+開關(guān)穩(wěn)壓器規(guī)格書PDF中文資料

L5150GJ屬于集成電路（IC）的線性+開關(guān)穩(wěn)壓器。由意法半導(dǎo)體集團(tuán)制造生產(chǎn)的L5150GJ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(fù)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(gè)最小量，并且在工作時(shí)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。

Description

L5150GJ is a low dropout linear regulator with microprocessor control functions such as power on reset, low voltage reset, early warning, on/off control. Typical quiescent current is 55 μA in very low output current mode and enabled regulator. It drops to 5 μA with not enabled regulator.

■ Operating DC supply voltage range 5.6 V to 40 V

■ Low dropout voltage

■ Low quiescent current consumption

■ Precision output voltage 5 V +/- 2

■ Reset circuit sensing the output voltage

■ Programmable reset pulse delay with external capacitor

■ Adjustable reset threshold

■ Early warning

■ Very wide stability range with low value output capacitor

■ Thermal shutdown and short-circuit protection

■ Wide temperature range (Tj = -40 °C to 150 °C)

■ Enable input for enabling / disabling the voltage regulator
