The V78XX-500-SMT series, a surface-mount version of the company’s 0.5-A V78XX-500 dc-switching regulator, offers 96% efficiency and is an alternative to linear regulators. It does not require a heat sink, and is suitable for applications that have restricted board space.
The V78XX-500-SMT series is compact, measuring 15.24 x 8.50 x 7.00 mm. A wide input range is available from 4.5 to 28 Vdc and regulated output voltages of 3.3, 5, 12, and 15 Vdc are offered. Output current is 500 mA with an operating temperature range of –40° to 71°C at 100% load, derating to 60% load at 85°C. The converters offer short-circuit protection, thermal shutdown, and an MTBF of 2 million hours. ($8.24 each — available now.)
