GENERAL DESCRIPTION

The SGM2022 is a dual, low-power, low-dropout, CMOS linear voltage regulators. It operates from a 2.5V to 4.5V input and delivers up to 150mA at each channel. The SGM2022 is the perfect choice for low voltage, low power and RF applications. A low ground current 160µA (both LDO’s enabled and active) makes this part attractive for battery operated power systems. The SGM2022 also offers low dropout voltage (135mV at 150mA output) to prolong battery life in portable electronics.
