MIC39100/39101/39102
1A Low-Voltage Low-Dropout Regulator
General Description
TheMIC39100,MIC39101,andMIC39102are1Alow-dropout
linearvoltageregulatorsthatprovidelow-voltage,high-current
outputfromanextremelysmallpackage.UtilizingMicrel’spro-
prietary Super βeta PNP pass element, the MIC39100/1/2
offers extremely low dropout (typically 410mV at 1A) and low
ground current (typically 11mA at 1A).
The MIC39100 is a xed output regulator offered in the
SOT-223 package. The MIC39101 and MIC39102 are xed
and adjustable regulators, respectively, in a thermally en-
hanced power 8-lead SOIC package.
The MIC39100/1/2 is ideal for PC add-in cards that need to
convert from standard 5V to 3.3V, 3.3V to 2.5V or 2.5V to
1.8V.Aguaranteed maximum dropout voltage of 630mV over
all operating conditions allows the MIC39100/1/2 to provide
2.5V from a supply as low as 3.13V and 1.8V from a supply
as low as 2.43V.
The MIC39100/1/2 is fully protected with overcurrent limit-
ing, thermal shutdown, and reversed-battery protection.
Fixed voltages of 5.0V, 3.3V, 2.5V, and 1.8V are available
on MIC39100/1 with adjustable output voltages to 1.24V on
MIC39102.
For other voltages, contact Micrel.
