MIC5365-1.0YC5集成电路（IC）的线性+开关稳压器规格书PDF中文资料

MIC5365-1.0YC5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MIC5365-1.0YC5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。

General Description

The MIC5365/6 is an advanced general purpose linear regulator offering high power supply rejection (PSRR) in an ultra-small 1mm x 1mm package. The MIC5366 includes an auto-discharge feature that is activated when the enable pin is low. The MIC5365/6 is capable of sourcing 150mA output current and offers high PSRR making it an ideal solution for any portable electronic application.

Ideal for battery-powered applications, the MIC5365/6 offers 2% initial accuracy, low dropout voltage (155mV @ 150mA), and low ground current (typically 29μA). The MIC5365/6 can also be put into a zero-off-mode current state, drawing virtually no current when disabled.

The MIC5365/6 is available in several advanced packages including a lead-free (RoHS-compliant) 1mm x 1mm Thin MLF® occupying only 1mm2 of PCB area, a 75% reduction in board area compared to SC-70 and 2mm x 2mm MLF® packages. It is also available in a thin SOT23-5 package.

The MIC5365/6 has an operating junction temperature range of –40°C to 125°C.
