ANALOG DEVICES LT1302CN8-5#PBF DC-DC Switching Boost Regulator, Fixed, 2 to 8V in, 5 V/2 A out, NDIP-8

LT1302-5 is a micropower step-up DC/DC converter that maintain high efficiency over a wide range of output current. They operate from a supply voltage as low as 2V and feature automatic shifting between Burst Mode operation at light load, and current mode operation at heavy load. The internal low loss NPN power switch can handle current in excess of 2A and switch at frequencies upto 400KHz. Quiescent current is just 200µA and can be further reduced to 15µA in shutdown. It is widely used in application such as notebook and palmtop computers, portable instruments, personal digital assistants, cellular telephones, flash memory etc.
