ISL9007 is a high performance LDO that delivers a continuous 400mA of load current. It has a low standby current and high PSRR and is stable with output capacitance of 1μF to 10μF with an ESR of up to 200mΩ.

The ISL9007 has a very high PSRR of 75dB and output noise less than 30μVRMS. When coupled with a no load quiescent current of 50μA (typical), and 1μA (max) shutdown current, the ISL9007 is an ideal choice for portable wireless equipment.

The ISL9007 comes in fixed voltage options of 3.3V, 2.85V, 2.8V, and 2.5V with ±1.8 output voltage accuracy over-temperature, line and load. Other output voltage options may be available upon request.

ISL9007IUNZ屬于集成電路（IC） > 線性 + 開關穩(wěn)壓器。瑞薩科技有限公司制造生產的ISL9007IUNZ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換為熱量。對于大多數(shù)應用而言，雖然這種穩(wěn)壓器的效率低于開關模式的穩(wěn)壓器，但它們通常更適合對噪聲高度敏感的應用。
