GENERAL DESCRIPTION

The SG2012 low-power, low-dropout, CMOS linear voltage regulators operate from a 2.5V to 5.5V input and deliver up to 400mA. They are perfect choice for low voltage, low power applications. An ultra low ground current (120µA at 400mA output) makes them attractive for battery operated power systems. The SG2012 series also offer ultra low dropout voltage (280mV at 400mA output) to prolong battery life in portable electronics.
