MCP1701A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 MCP1701A is a CMOS low dropout positive voltage regulator with a maximum input voltage of 10V that can source up to 250 mA with a low input to output voltage differential of 380 mV at 200 mA. This low dropout voltage combined with low current consumption of 1.0 µA typical makes this part ideal for battery operated systems. This part is recommended for applications where the input voltage is between 6.0V and 10.0V. For applications where input voltages are less than 6.0V, Microchip recommends the MCP1700. The MCP1701A is offered in SOT-23-3, SOT-89-3 and TO-92-3 packages.

简介

MCP1701A属于集成电路（IC）的线性+开关稳压器。由制造生产的MCP1701A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。
