DESCRIPTION
The SGM2042 is a dual low dropout CMOS regulator with low RDS(ON), high PSRR, low output noise and low quiescent current.
Each of the two regulators includes an error amplifier and current limit circuit. With the integrated resistor network, fixed output voltage versions can be delivered. With its low power consumption and fast line and load transient responses, the SGM2042 is well suited for low power handheld communication equipment.
The SGM2042 is available in a Green UTDFN-1×1-4AL package, and allows for small footprint and dense PCB layout. It operates over an ambient temperature range of -40℃ to +85℃.
