The different versions of this regulator all look very similar, so the bottom silkscreen includes a blank space where you can add your own distinguishing marks or labels. This prod uct page applies to all eight versions of the D24V5Fx family. The regulators feature short-circuit/over-current protection, and thermal shutdown helps prevent damage from overheating. The boards do not have reverse-voltage protection. If you need more output current, consider the very similar D24V10Fx family of step-down voltage regulators, which can deliver up to 1 A in several different output voltages: The picture on the right shows a 1 A D24V10Fx regulator next to a 0.5 A D24V5Fx regulator and a common 7805 linear regulator in a TO-220 package. Features Input voltage: 3 V to 36 V for output voltages of 1.8 V and 2.5 V [output voltage + dropout voltage] to 36 V for output voltages of 3.3 V and higher (see below for more information on dropout voltage) Fixed 1.8 V, 2.5 V, 3.3 V, 5 V, 6 V, 9 V, 12 V, or 15 V output (depending on regulator version) with 4% accuracy Maximum output current: 500 mA Typical efficiency of 80% to 93% 500 kHz switching frequency (when not in power-save mode) 200 μA typical no-load quiescent current Integrated over-temperature and over-current shutoff Small size: 0.5″ × 0.4″ × 0.1″ (13 mm × 10 mm × 3 mm) Show more
