Overview

The LT1073CS8#PBF is a versatile gated-oscillator switching regulator that can be configured for buck, boost, or inverting topologies. It operates with a very low supply current and is designed specifically to work with single-cell inputs, functioning down to 1V. The device includes an internal 1.5A power switch and requires very few external components for a complete power solution.

Why Choose This Part

This regulator stands out for its ability to start and operate from inputs as low as 1V, making it ideal for single-cell battery applications. The 1.5A internal switch allows for higher power delivery than typical micropower regulators while maintaining a low 95uA quiescent current. Its flexible architecture supports multiple configurations including step-up, step-down, and inverting modes using the same IC.

Applications

Single-Cell Battery Step-Up
Converting 1V or 1.5V alkaline cell outputs to a regulated 3V or 5V rail for low-power electronics.
Negative Voltage Generation
Configuring the device in an inverting topology to provide negative bias rails from a positive input voltage.
Remote Instrumentation
Powering sensors and data loggers in applications where minimal standby current is critical for battery longevity.

Getting Started

When designing with the LT1073, ensure the inductor selection accounts for the peak switch current to prevent saturation. Use low-ESR capacitors to minimize output ripple, especially in boost configurations. Reference the datasheet's application circuits for specific component values when setting the output voltage via the gain block and feedback pin.
