Micrel MIC5501-2.8YMT Single 300ma ldo Datasheet

MIC5501/2/3/4
Single 300mA LDO
Revision 2.0
General Description
Features
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 highperformance 300mA LDO in an ultra-small 1mm x 1mm
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.
Ideal for battery-powered applications, the MIC5501/2/3/4
offers 2% initial accuracy, low dropout voltage (160mV at
300mA), and low ground current (typically 38µA). The
MIC5501/2/3/4 can also be put into a zero-off-mode
current state, drawing virtually no current when disabled.
The MIC5501/2/3/4 has an operating junction temperature
range of –40°C to 125°C.
