STLQ015M20R集成電路（IC）的線性+開關(guān)穩(wěn)壓器規(guī)格書PDF中文資料

STLQ015M20R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STLQ015M20R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(huì)將輸入端的任何多余電壓轉(zhuǎn)換為熱量。對(duì)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(duì)噪聲高度敏感的應(yīng)用。

Description

The STLQ015 provides 150 mA of maximum current with an input voltage range from

1.5 V to 5.5 V and a typical dropout voltage of 112 mV. The key feature of this device

is its quiescent current, which is just 1.4 μA at maximum output current.The device is

stable with a ceramic capacitor on the output. It offers very low quiescent current and

extends battery-life of applications requiring very long standby time. The enable logic

control function puts the STLQ015 in shutdown mode, reducing total current

consumption to 1 nA. The device also includes short-circuit constant-current limiting

and thermal protection. Typical applications are: portable and battery-powered

systems, electronic sensors and microcontroller power supply.
