ADM7170規(guī)格書(shū)詳情

ADM7170屬于集成電路(IC)的線性+開(kāi)關(guān)穩(wěn)壓器。由亞德諾半導(dǎo)體技術(shù)有限公司制造生產(chǎn)的ADM7170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(wú)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(kāi)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。

GENERAL DESCRIPTION

The ADM7170 is a CMOS, low dropout linear regulator (LDO) that operates from 2.3 V to 6.5 V and provides up to 500 mA of output current. This high output current LDO is ideal for regulation of high performance analog and mixed signal circuits operating from 6 V down to 1.2 V rails. Using an advanced proprietary architecture, the device provides high power supply rejection and low noise, and achieves excellent line and load transient response with just a small 4.7 μF ceramic output capacitor. Load transient response is typically 1.5 μs for a 1 mA to 500 mA load step.

The ADM7170 is available in 17 fixed output voltage options. The following voltages are available from stock: 1.3 V, 1.8 V, 2.5 V, 3.0 V, 3.3 V, 4.2 V, and 5.0 V. Additional voltages that are available by special order are: 1.5 V, 1.85 V, 2.0 V, 2.2 V, 2.7 V, 2.75 V, 2.8 V, 2.85 V, 3.8 V, and 4.6 V. An adjustable version is also available that allows output voltages that range from 1.2 V to VIN ? VDO with an external feedback divider.

Inrush current can be controlled by adjusting the start-up time via the soft start pin. The typical start-up time with a 1 nF soft start capacitor is about 1.0 ms.

The ADM7170 regulator output noise is 5 μV rms independent of the output voltage. The ADM7170 is available in an 8-lead, 3 mm × 3 mm LFCSP, making it not only a very compact solution, but also providing excellent thermal performance for applications requiring up to 500 mA of output current in a small, low profile footprint.
