RP202数据手册集成电路（IC）的线性+开关稳压器规格书PDF

描述 Description

The RP202 Series are CMOS-based auto ECO mode switching LDO regulators featuring 200mA output. In auto switching mode, the operation can switch automatically to fast response mode or low power mode of the ECO function according to output current. (Automatic switching to fast response mode under IOUT > 8mA conditions or to low power mode under IOUT In low power mode, supply current is as low as 2.5µA. In fast response mode, ripple rejection is 70dB and noise is low. RP202 requires neither ECO pin for switching mode nor microcontroller pin. RP202 supports low voltage, featuring input voltage from 1.4V and output voltage from 0.8V. Standby mode and auto-discharge function are also available. In addition to SOT-23-5 and SC-88A packages, and a 1mm square DFN(PLP)1010-4 are also available.

简介

RP202属于集成电路（IC）的线性+开关稳压器。由制造生产的RP202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。
