描述 Description

The RP116 Series are CMOS-based LDO regulators featuring 400mA output. The input voltage as low as Min. 1.0V and the output voltage can be set from 0.7V. The output voltage accuracy has been improved to ± 0.8% and due to a built-in transistor with low on-resistance of 0.55Ω (at VSET=1.5V), RP116 provides a low dropout voltage. The CE pin can switch the regulator to standby mode. RP116 has a constant slope circuit. It means a function of soft-start to reduce the inrush current at power on.

RP116 is available in 0.69mm square WLCSP-4-P7 package. RP116Z (WLCSP-4-P7) is thiner than RP106Z (WLCSP-4-P5). (t=0.36mm)

簡介

RP116屬于集成電路（IC）的穩(wěn)壓器-線性。由制造生產(chǎn)的RP116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(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。
