LT1073CS8#PBF

LT1073CS8#PBF is a versatile micropower DC/DC converter. This 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 device 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. Average current drain of the device is just 135µA unloaded, making it ideal for applications where long battery life is important. The device can easily be configured as a step-up or stepdown converter, although for most step-down applications or input sources greater than 3V, the LT1173 is recommended. It is used in application like pagers, cameras, single-cell to 5V converters, battery backup supplies, laptop and palmtop computers, cellular telephones, portable instruments, 4mA to 20mA loop powered instruments, hand-held inventory computers, battery-powered α, β, and γ particle detectors etc.
