n Space-Saving 8-Pin PDIP or SO-8 Package 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. n APPLICATIONS
