MCP1711中文资料150 mA Ultra-Low Iq, Capless LDO Regulator数据手册Microchip规格书

描述 Description

The MCP1711 is a very accurate CMOS low dropout (LDO) voltage regulator that can deliver up to 150 mA of current while consuming only 0.6 μA of quiescent current (typical). The LDO output is stable without the need of capacitors due to excellent internal phase compensation. Eliminating capacitors can save space overall solution cost. However, for better transient responses, the output capacitor should be added for enhanced performance. The MCP1711 has a true current foldback feature for added protection when the load decreases beyond the MCP1711’s load rating. The package options for the MCP1711 are the 4-Lead 1x1 mm UQFN and the 5-Lead SOT-23 which makes an ideal choice for small and compact applications.

简介

MCP1711属于集成电路（IC）的线性+开关稳压器。由制造生产的MCP1711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。
