LP2985-30DBVTG4規(guī)格書詳情

LP2985-30DBVTG4屬于集成電路(IC)的線性+開關(guān)穩(wěn)壓器。由德州儀器制造生產(chǎn)的LP2985-30DBVTG4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。

3 Description

The LP2985 is a fixed-output, wide-input, low-noise,

low-dropout voltage regulator supporting an input

voltage range from 2.5 V to 16 V and up to 150 mA of

load current. The LP2985 supports an output range of

1.2 V to 5.0 V (for new chip).

Additionally, the LP2985 (new chip) has a 1 output

accuracy across load, and temperature that can meet

the needs of low-voltage microcontrollers (MCUs) and

processors.

Low output noise of 30 μVRMS (with 10-nF bypass

capacitors) and wide bandwidth PSRR performance

of greater than 70 dB at 1 kHz and 40 dB at 1 MHz

help attenuate the switching frequency of an upstream

DC/DC converter and minimize post regulator filtering.

The internal soft-start time and current limit protection

reduce inrush current during start up, thus minimizing

input capacitance. Standard protection features, such

as overcurrent and overtemperature protection, are

included.

The LP2985 is available in a 5-pin 2.9-mm × 1.6-mm

SOT-23 (DBV) package.
