MCP1703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 MCP1703 is a CMOS, low dropout voltage regulator with 250 mA maximum output current. MCP1703 works with input voltage of up to 16V and in combination with its low current consumption of 2 µA is an ideal solution for applications using multi-cell, 9V alkaline or one-, two- or three- cell lithium-ion batteries. It is available in space efficient SOT23A and SOT89 packages or in a thermally capable 3-pin SOT223.For new designs, please consider the MCP1703A, which contains several improvements over the MCP1703.

简介

MCP1703属于集成电路（IC）的线性+开关稳压器。由制造生产的MCP1703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。
