LT1073CN8-5 Datasheet PDF - Linear Technology

DESCRIPTION

●The LT®1073 is a versatile micropower DC/DC converter. The device requires only three external components to deliver a fixed output of 5V or 12V. The very low minimum supply voltage of 1V allows the use of the LT1073 in applications where the primary power source is a single cell. An on-chip auxiliary gain block can function as a low battery detector or linear post-regulator.
