DESCRIPTION

The LX8630 family are positive very low dropout regulators. They are 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 150mΩ resulting in a typical dropout voltage of 450mV at 3A.

KEY FEATURES

◾ Dropout Voltage Typically 450mV at 3A and 50mV at 10mA

◾ Low Quiescent Current, Typically Under 400µA, irrespective of Load

◾ Shutdown Current 10µA

◾ Adjustable Output Version in 5-Pin TO-220 & TO-263 Packages

◾ Low Reverse Leakage Current

◾ Short-Circuit and Thermal Shutdown Protection

APPLICATIONS/BENEFITS

◾ 3.3V & 2.5V Supplies for Memory, Microprocessors, Clock Circuits, Etc.

◾ Portable Equipment
