DESCRIPTION
The LD2982 is a 50mA fixed output voltage regulator. The ultra low drop voltage and the low quiescent current make them particularly suitable for low noise, low power applications, and in battery powered systems. In sleep mode quiescent current is less than 1μA when INHIBIT pin is pulled low. Shutdown Logic Control Function is available on pin 3 (TTL compatible). This means that when the device is used as local regulator, it is possible to put a part of the board in standby, decreasing the total power consumption.
An external capacitor CBYP=10nF connected between bypass pin and GND reduce the noise to 30μVrms.
Typical application are in cellular phone, palmtop/laptop computer, personal digital assistant (PDA), personal stereo, camcorder and camera.
■ VERY LOW DROPOUT VOLTAGE (120mV AT 50mA AND 7mV AT 1mA LOAD)
■ VERY LOW QUIESCENT CURRENT (375μA TYP. AT 50mA LOAD AND 75μA AT 1mA)

■ LOW OUTPUT NOISE VOLTAGE 30μVrms
■ SMALLEST PACKAGE SOT23-5L
■ TEMPERATURE RANGE: -40°C TO 125°C
LD2982BM18R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LD2982BM18R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。
