The LM37100/1/2 is 1A low-dropout linear voltage regulators that provide low-voltage, high-current output. The
LM37100/1/2 offers extremely low dropout (typically 470mV at 1A) and low ground current (typically 12mA at
1A). The LM37100/1 and LM37102 are fixed and adjustable regulators, respectively, in SOT-223, SOP-8 and
TO-252 Package.
The LM37100/1/2 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
LM37100/1/2 to provide2.5V from a supply as low as 3.13V and 1.8V from a supply as low as 2.43V. The
LM37100/1/2 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 LM37100/1 with adjustable output voltages
to 1.24V on LM37102.
