LM39100/1/2

HTC Korea LM39100, LM39101, and LM39102 are 1A low-dropout linear voltage regulators that provide low-voltage, high-current output from an extremely small package. 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 in 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 to 1.8V. A guaranteed maximum dropout voltage of 630mV overall operating conditions allows the LM39100/1/2 to provide 2.5V from a supply as low as 3.13V and 1.8V from a supply as low as 2.43V. The 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.
