onsemi NCP5974x Ultra-Low Dropout Voltage Regulators
onsemi NCP5974x Ultra-Low Dropout Voltage Regulators are dual-rail, low dropout linear regulators capable of providing an output current in excess of 1.5/3A with a dropout voltage of 60/115/120mV typ. at full load current. The devices are stable with ceramic and other types of output capacitors. Internal protection features include built−in thermal shutdown and output current limiting protection. QFN and DFN versions include user programmable soft−start and power good pins. onsemi NCP5974x Ultra-Low Dropout Voltage Regulators are well-suited for computing and peripherals, medical, consumer, and applications with specific start−up time or sequencing requirements.
