MIC5514

MIC5512/14 Single 300mA LDO in 1.6mm × 1.6mm Thin DFN Package General Description The MIC5512/14 is an advanced general-purpose LDO ideal for powering general-purpose portable devices. The MIC5512/14 family of products provides a highperformance 300mA LDO in an ultra-small 1.6mm x 1.6mm Thin DFN package. The MIC5512 and MIC5514 LDOs include an auto-discharge feature on the output that is activated when the enable pin is low. The MIC5514 have an internal pull down resistor on the enable pin that will disable 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 MIC5512/14 offers a typical 1% initial accuracy, low dropout voltage (160mV at 300mA), and low ground current (typically 38µA). The MIC5512/14 can also be put into a zero-offmode current state, drawing virtually no current when disabled. The MIC5512/14 has an operating junction temperature range of –40°C to 125°C.
