DESCRIPSION
The LM39100/1/2 is 1A low-dropout linear voltage regulators that provide low-voltage, high-current output. The LM39100/1/2 offers extremely low dropout (typically410mV at 1A) and low ground current (typically 12mA at 1A). The LM39100 is a fixed outputregulator offered in the SOT-223 package. The LM39101 and LM39102 are fixed and adjustable regulators, respectively, in SOP-8 and TO-252 Packages.
