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.

The output voltage is preset to voltages in the range of

1.5V to 4.5V. Other features include

limit

SG2012 comes in 3-pin SOT223 package.
