MIC5504-2.8YM5-TR

低压差稳压器 Single 300mA LDO

300 mA Single Output LDO in Small Packages

General Description MIC5504-2.8YM5-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.
