LX8630-xx
3A BiCMOS Very Low Dropout
Regulators
P RODUCTION D ATA S HEET
The LX8630 family are positive very They are low dropout
regulators.
designed to provide a power supply for very low headroom applications, such as 3.
3V – 2.
5V.
BiCMOS technology allows an effective series pass element resistance, RDS(ON) of 150m
dropout voltage of 450mV at 3A.
Low Quiescent Current and LogicControlled Shutdown help conserve battery life and increase system efficiency.
Typical quiescent current is under 400A irrespective of load current, while the
Shut
device will enter shutdown mode when...
