Wide VIN Range Step-Down Regulators Consume Only 2.8µA Input Current

December 01, 2011 // By Electronics EETimes

Battery life is paramount in modern battery-powered systems. Portable applications, such as remote sensors, require voltage regulators which have low current standby states and also able to provide bursts of high power. Linear Technology's LT®3970/LT3971 lead the industry in low current standby mode by consuming only 2.8uA of input current when regulating a 3.3V output with no load. The LT3970 and LT3971 have quiescent currents less than the self discharge rates of most batteries.
