Description
The UC2975 is a switching voltage regulator designed for electronic components. It can deliver a fixed output voltage from an input voltage supply of 2.7V to 5.5V. With its proprietary architecture and synchronous rectification, the UC2975 achieves a peak efficiency of 96% and maintains efficiency over 90% with load currents as low as 1mA. It also seamlessly transitions into and out of 100% duty cycle operation when the supply dips, ensuring smooth regulation without overshoot.
