Product Summary
The LT1073CS8-5#TRPBF 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 1.0V allows the use of the LT1073CS8-5#TRPBF 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 LT1073CS8-5#TRPBF used as shown in the Typical Application circuit below is just 135(xA unloaded, making it ideal for applications where long battery life is important. The applications of the LT1073CS8-5#TRPBF include Pagers, Cameras, Single-Cell to 5V Converters, Battery Backup Supplies, Laptop and Palmtop Computers, CellularTelephones, Portable Instruments, 4mA-20mA Loop Powered Instruments, Hand-Held Inventory Computers, Battery-Powered α, β, γ Particle Detectors.
