Make tailoring direct current to your needs a snip with this power switching regulator from Traco Power. It's an ideal choice for low-power applications, as it uses an input voltage between 6.5 and 42V DC to generate a 5V DC output. As it's a SIP-type package, its components are parcelled up efficiently inside compact dimensions of 11.7 (L) x 7.5 (W) x 10.2mm (D), so it fits neatly into busy setups. Inbuilt overtemperature and short-circuit protections fend off electrical hazards, while the UL 94 V-0-rated silicone potting self-extinguishes within 10 seconds to boost workplace safety. The regulator's plastic housing withstands impacts and abrasion to deliver a long service life.
