MIC5512/14 Single 300mA LDO in 1.6mm × 1.6mm Thin DFN Package General Description Features The MIC5512/14 is an advanced general-purpose LDO • Input voltage range: 2.5V to 5.5V ideal for powering general-purpose portable devices. The • Fixed output voltage range: 1.0V to 3.3V MIC5512/14 family of products provides a high• 300mA guaranteed output current performance 300mA LDO in an ultra-small 1.6mm x • ±1% initial output accuracy 1.6mm Thin DFN package. The MIC5512 and MIC5514 • Stable with 1µF ceramic output capacitors LDOs include an auto-discharge feature on the output that is activated when the enable pin is low. The MIC5514 have • Low dropout voltage: 160mV @ 300mA an internal pull down resistor on the enable pin that will • Output discharge circuit disable the output when the enable pin is left floating, this • Internal enable pull down resistor (MIC5514) is ideal for applications where the control signal is floating • Available in ultra-small 6-pin 1.6mm × 1.6mm Thin DFN during processor boot up. package Ideal for battery-powered applications, the MIC5512/14 offers a typical 1% initial accuracy, low dropout voltage Applications (160mV at 300mA), and low ground current (typically • Smart phones 38µA). The MIC5512/14 can also be put into a zero-off• DSCs, GPS, PMPs, and PDAs mode current state, drawing virtually no current when disabled. • Medical devices The MIC5512/14 has an operating junction temperature • Portable electronics range of –40°C to 125°C. • 5V systems Data sheets and support documentation can be found on Micrel’s web site at: www.micrel.com. ___________________________________________________________________________________________________________ Typical Application Micrel Inc. • 2180 Fortune Drive • San Jose, CA 95131 • USA • tel +1 (408) 944-0800 • fax + 1 (408) 474-1000 • http://www.micrel.com April 8, 2013 Revision 1.1 Micrel, Inc.

Exceeding the absolute maximum rating may damage the device. 2. The device is not guaranteed to function outside its operating rating. 3. The maximum allowable power dissipation of any TA (ambient temperature) is PD(max) = (TJ(max) – TA) / θJA. Exceeding the maximum allowable power dissipation will result in excessive die temperature, and the regulator will go into thermal shutdown. 4. Devices are ESD sensitive. Handling precautions are recommended. Human body model, 1.5kΩ in series with 100pF. 5. Other voltages are available. Contact Micrel for details.
