MIC5501-3.0YM5-TR 稳压器LDO Microchip

MIC5501-3.0YM5-TR

300 mA Single Output LDO in Small Packages

低压差稳压器 General Purpose Single 300mA LDO

General Description MIC5501-3.0YM5-TR

The MIC5501/2/3/4 is an advanced general-purpose LDO ideal for powering general-purpose portable devices. The MIC5501/2/3/4 family of products provides a high-performance 300 mA LDO in an ultra-small 1 mm x 1 mm package. The MIC5502 and MIC5504 LDOs include an auto-discharge feature on the output that is activated when the enable pin is low. The MIC5503 and MIC5504 have an internal pull-down resistor on the enable pin that disables the output when the enable pin is left floating. This is ideal for applications where the control signal is floating during processor boot up.
