The R420 has been designed for auxiliary power from 4-20mA loops and other low power budget applications that require a maximum input current <3.6mA. This low profile SMD converter delivers a regulated, short circuit protected output that can be adjusted between 1.8V & 5V with a single external resistor & delivers three times the output current of equivalent linear regulators to power microprocessors, data loggers & HART digital modems without affecting the analog 4-20mA signal. The R420 will also find many applications in energy scavenging & indoor solar powered circuits.
