描述 Description

The RP101 Series are CMOS-based LDO regulators featuring 300mA output. RP101 has the supply current as low as 18μA, which is far lower than current products. Due to a built-in transistor with low on-resistance of 0.87Ω (at VSET=2.8V) , RP101 provides a low dropout voltage. RP101 also has an excellent line transient response, 75dB ripple rejection, and low noise. The output voltage accuracy has been improved to ± 0.6% and the temparature drift coefficient of the output voltage is as low as ± 30ppm/°C.

簡介

RP101屬于集成電路（IC）的穩(wěn)壓器-線性。由制造生產(chǎn)的RP101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。
