Description

The LD39015xx series provides 150 mA maximum current from an input voltage ranging from 1.5 V to 5.5 V with a typical dropout voltage of 80 mV. It is stable with ceramic capacitor. The ultra-low drop voltage, low quiescent current and low noise features make it suitable for low power battery-powered applications.

Features

■ Input voltage from 1.5 to 5.5 V

■ Ultra low dropout voltage (80 mV typ. at 100 mA load)

■ Very low quiescent current (18 μA typ. at no load, 35 μA typ. at 150 mA load, 1 μA max in off mode)

■ Very low noise without bypass capacitor (29 μVRMS at VOUT = 0.8 V)

■ Output voltage tolerance: ± 2.0 @ 25 °C

■ 150 mA guaranteed output current

■ Wide range of output voltages available on request: 0.8 V to 3.3 V with 100 mV step

■ Logic-controlled electronic shutdown

■ Compatible with ceramic capacitors CO = 1 μF

■ Internal current and thermal limit

■ Available in SOT666 and SOT23-5L packages

■ Temperature range: -40 °C to 125 °C

LD39015M33R屬于集成電路（IC） > 線性 + 開關(guān)穩(wěn)壓器。意法半導(dǎo)體（ST）集團(tuán)制造生產(chǎn)的LD39015M33R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。
