LP3905 Power Management Unit For Low Power Handheld Applications
August 2006
LP3905
Power Management Unit For Low Power Handheld
Applications
General Description
LP3905 is a multi-functional Power Management Unit,
optimized for low power handheld applications. This device
integrates two 600mA DC/DC buck regulators and two
150mA linear regulators. Fixed and adjustable buck output
versions are available. The LP3905 additionally features two
enable pins for the device output control and is offered in an
LLP package.
