Recom Switching Regulator, Through Hole, 3.3V dc Output Voltage, 7 → 42V dc Input Voltage, 1A Output Current, 1

Control the output voltage of your battery-powered devices with this switching regulator from RECOM. As it has a wide input voltage range between 7 and 42V DC, it's a versatile option that handles many common power supplies, converting them to a 3.3V DC output. With its built-in short circuit protection, the unit automatically recovers after electrical faults to minimise appliance downtime. A line regulation rating of ±0.2% means it provides a steady output voltage, so you can be sure of a reliable power supply.
