SOP-8
The LM39100/1/2 is 1A low-dropout linear voltage
X.X = Output Voltage = 1.5, 1.8, 2.5, 3.3, 5.0
regulators that provide low-voltage, high-current output.
The LM39100/1/2 offers extremely low dropout (typically 410mV at 1A) and low ground current (typically 12mA
at 1A). The LM39100 is a fixed output regulator offered in the SOT-223 package. The LM39101 and LM39102
are fixed and adjustable regulators, respectively, in SOP-8 and TO-252 Packages.
The LM39100/1/2 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 to1.8V. A guaranteed maximum dropout voltage of 630mV overall operating conditions allows the
LM39100/1/2 to provide2.5V from a supply as low as 3.13V and 1.8V from a supply as low as 2.43V. The
LM39100/1/2 is fully protected with over current limiting, thermal shutdown, and reversed-battery protection.
Fixed voltages of 5.0V, 3.3V, 2.5V, 1.8V and 1.5V are available on LM39100/1 with adjustable output voltages
to 1.24V on LM39102.
