RP116数据手册集成电路（IC）的稳压器-线性规格书PDF

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)

简介

RP116属于集成电路（IC）的稳压器-线性。由制造生产的RP116稳压器 - 线性线性稳压器用于提供稳定的输出电压，无论负载电流、输入电压或环境因素如何变化，这些输出电压通常都要保持不变。它们的工作原理要求输入电压维持在高于所需的输出电压，而且要超出某个最小量，并且在工作时会将输入端的任何多余电压转换为热量。对于大多数应用而言，虽然这种稳压器的效率低于开关模式的稳压器，但它们通常更适合对噪声高度敏感的应用。
