We are happy to introduce our D24V5Fx voltage regulator family, a next-generation version of our tiny D24V3Fx and D24V6Fx buck (step-down) regulators, which have been some of our most popular products. These new regulators are synchronous, which results in better efficiency, especially at light loads, and they have much lower dropout voltages (e.g. the 5 V version has just over 1 mV of dropout per mA of output current).
So far we have versions with 3.3 V, 5 V, 9 V, and 12 V outputs, and we will soon be releasing 1.8 V, 2.5 V, and 6 V versions; you can contact us for custom voltages, too. They operate with input voltages up to 36 V and have typical efficiencies of 80% to 93%. These regulators have integrated over-temperature and over-current shutoff, and they reduce their switching frequency from the typical 500 kHz to improve efficiency at light loads, making them well suited for low-power applications that are run from a battery.
At only 0.5″ × 0.4″ × 0.1″ (13 mm × 10 mm × 3 mm) these buck regulators are also smaller than standard through hole linear regulators with DIP packages. The picture below shows a D24V5Fx next to a 7805 voltage regulator in a TO-220 package.
