General Description
The MIC37100, MIC37101, and MIC37102 are 1A low-
dropout, linear voltage regulators that provide low-voltage,
high-current output from an extremely small package.
Utilizing Micrel’s proprietary Super βeta PNP
pass
element, the MIC37100/01/02 offers extremely low dropout
(typically 280mV at 1A) and low ground current (typically
11mA at 1A).
The MIC37100 is a xed output regulator offered in the
SOT-223 package. The MIC37101 and MIC37102 are
xed and adjustable regulators, respectively, in a thermally
enhanced power 8-pin SOIC (small outline package) and
the SOT-223 package. The MIC37102 is also available in
the S-PAK power package, for applications that require
higher power dissipation or higher operating ambient
temperatures.
The MIC37100/01/02 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 or lower. A guaranteed maximum dropout
voltage of 500mV over all operating conditions allows the
MIC37100/01/02 to provide 2.5V from a supply as low as
3V and 1.8V from a supply as low as 2.3V.
The MIC37100/01/02 is fully protected with overcurrent
limiting and thermal shutdown. Fixed output voltages of
1.5V, 1.65V, 1.8V, 2.5V and 3.3V are available on
MIC37100/01 with adjustable output voltages to 1.24V on
MIC37102.
