RP110数据手册集成电路（IC）的稳压器-线性规格书PDF

描述 Description

The RP110 Series are CMOS-based LDO regulators featuring 150mA output. The RP110's typical ultra low supply current of 1µA makes it ideal for use in power supply systems with the sleep mode on. The version that reduced supply current to the lowest possible level by eliminating the CE pin is also available. The input voltage (VIN) is as low as Min. 1.4V and the output voltage can be set from 0.8V. RP110 has a constant slope circuit. It means a function of soft-start to reduce the inrush current at power on.

In addition to SOT-23-5, SC-88A and DFN1010-4 packages, a 0.8mm square ultra compact DFN(PLP)0808-4 package is also available. RP110 Series contributes to the downsizing of the hand-held equipment because it can use the 0.1µF ceramic capacitor.

简介

RP110属于集成电路（IC）的稳压器-线性。由制造生产的RP110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。
