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 the SHDN pin is pulled low. Thermal and Short-Circuit Current Limiting: the LX8630 limits the current when the output is shorted, protecting the sensitive load circuits. The device will also turn off if the junction temperature exceeds 150° Available in Popular TO-220 and TO-263 Power Packages: adjustable versions have five leads, and fixed output voltage devices are supplied in three lead packages.
