MIC39100/39101/39102
1A Low-Voltage Low-Dropout Regulator
General Description
The MIC39100, MIC39101, and MIC39102 are 1A low-
dropout linear voltage regulators that provide low-voltage,
high-current output from an extremely small package. Utiliz-
ing Micrel’s proprietary Super
β
eta 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 fixed output regulator offered in the
SOT-223 package. The MIC39101 and MIC39102 are fixed
and adjustable regulators, respectively, in a thermally en-
hanced power 8-lead SOP (small outline 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. A guaranteed 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 limiting,
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.
