MCP1725T-1202E/SN集成电路（IC）的线性+开关稳压器规格书PDF中文资料

MCP1725T-1202E/SN属于集成电路（IC）的线性+开关稳压器。由微芯科技股份有限公司制造生产的MCP1725T-1202E/SN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。

Description

The MCP1725 is a 500 mA Low Dropout (LDO) linear regulator that provides high current and low output voltages in a very small package. The MCP1725 comes in a fixed (or adjustable) output voltage version, with an output voltage range of 0.8V to 5.0V. The 500 mA output current capability, combined with the low output voltage capability, make the MCP1725 a good choice for new sub-1.8V output voltage LDO applications that have high current demands.
