DESCRIPTION

The LD1585C is a LOW DROP Voltage Regulator able to provide up to 5A of Output Current. Dropout is guaranteed at a maximum of 1.4V at the maximum output current, decreasing at lower loads. The device has been improved to be utilized in low voltage applications where transient response and minimum input voltage are critical.

■ THREE TERMINAL ADJUSTABLE OR FIXED OUTPUT VOLTAGE 1.5V 1.8V, 2.5V, 2.85V, 3.3V, 5V, 8V, 9V, 12V.

■ GUARANTEED OUTPUT CURRENT UP TO 5A

■ OUPUT TOLERANCE ±1 AT 25°C AND ±2 IN FULL TEMPERATURE RANGE

■ INTERNAL POWER AND THERMAL LIMIT

■ WIDE OPERATING TEMPERATURE RANGE 0°C TO 125°C

■ PACKAGE AVAILABLE: TO-220, D2PAK, D2PAK/A

■ PINOUT COMPATIBILITY WITH STANDARD ADJUSTABLE VREG

LD1585CD2M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LD1585CD2M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，而且要超出某個最小量，并且在工作時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。
