描述 Description

The AAT2606 is a member of AnalogicTech’s Total Power Management IC? (TPMIC?) product family. It contains six fully integrated low dropout (LDO) regulators, making it ideal for general, compact applications.
The AAT2606 includes six low-noise, high PSRR LDOs, each of which is independently enabled. Any power up or power down sequencing is achievable by the host by controlling the independent enable pins. Each LDO requires only a small output ceramic capacitor for stability. Output voltages are programmed via an integrated One Time Programmable (OTP) process during manufacturing to provide output voltage per application requirement. All LDO input pins are tied together internally. The LDOs are low noise and have high PSRR (68dB at 10KHz).
The AAT2606 is available in the small 14-pin 3mm x 3mm TDFN package.

簡介

AAT2606屬于集成電路（IC）的線性+開關(guān)穩(wěn)壓器。由制造生產(chǎn)的AAT2606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。
