The Microchip MIC5504-1.8YM5-TR is an advanced general-purpose LDO ideal for powering general-purpose portable devices. The MIC5504-1.8YM5-TR provides a high-performance 300mA LDO in an ultra-small 1mm x 1mm package. The MIC5504-1.8YM5-TR LDOs include an auto-discharge feature on the output that is activated when the enable pin is low. The MIC5504-1.8YM5-TR 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. Ideal for battery-powered applications, the MIC5504-1.8YM5-TR offers 2% initial accuracy, low dropout voltage (160mV at 300mA), and low ground current (typically 38μA). The MIC5504-1.8YM5-TR can also be put into a zero-off-mode current state, drawing virtually no current when disabled. The MIC5504-1.8YM5-TR h
