MIC5504-3.1YMT T5 Microchip

MIC5501/2/3/4 Single 300mA LDO in 1.0mm 1.0mm DFN Package General Description Features The MIC5501/2/3/4 is an advanced general-purpose LDO Input voltage range: 2.5V to 5.5V ideal for powering general-purpose portable devices. The Fixed output voltages from 1.0V to 3.3V MIC5501/2/3/4 family of products provides a high- 300mA guaranteed output current performance 300mA LDO in an ultra-small 1mm 1mm High output accuracy (2%) package. The MIC5502 and MIC5504 LDOs include an auto-discharge feature on the output that is activated when Low quiescent current: 38A the enable pin is low. The MIC5503 and MIC5504 have an Stable with 1F ceramic output capacitors internal pull-down resistor on the enable pin that disables Low dropout voltage: 160mV 300mA the output when the enable pin is left floating. This is ideal Output discharge circuit: MIC5502, MIC5504 for applications where the control signal is floating during Internal enable pull-down: MIC5503, MIC5504 processor boot up. Thermal-shutdown and current-limit protection Ideal for battery-powered applications, the MIC5501/2/3/4 offers 2% initial accuracy, low dropout voltage (160mV at 4-lead 1.0mm 1.0mm Thin DFN package 300mA), and low ground current (typically 38A). The MIC5504 5-pin SOT23 package MIC5501/2/3/4 can also be put into a zero-off-mode current state, drawing virtually no current when disabled. Applications The MIC5501/2/3/4 has an operating junction temperature range of 40C to 125C. Smartphones Datasheets and support documentation can be found on DSC, GPS, PMP, and PDAs .
