RECOM R420 Low-Current Switching Regulator | DigiKey Daily

RECOM Power's R420 is a low-current switching regulator that has been designed for auxiliary power from 4 mA to 20 mA loop operation and energy scavenging applications. This low-profile, open-frame SMD converter has no minimum load requirement and delivers a continuous, regulated, short-circuit protected output that can be adjusted between 1.8 V and 5 V with a single external resistor. It delivers three times the output current of equivalent linear regulators to power microprocessors, data-loggers, and HART digital modems. The R420 will also find many applications in energy scavenging and indoor solar-powered circuits.
