3.3V/10mA Regulator from a 4mA to 20mA Loop

Apr 4th 1997
This circuit is a 3.3V/10mA regulator that extracts its power from a 4mA to 20mA loop. This circuit demonstrates how an LTC1474/LTC1475-based regulator is easily optimized for such low current applications . The 2W sense resistor limits the peak inductor current to 40mA to minimize current ripple and provide good efficiency ...
