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 (linear.com/product/LT3970) 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. These products can provide up to 1.2A and 350mA of output current at high efficiencies from inputs of up to 38V. The LT3970 and LT3971 have quiescent currents less than the self discharge rates of most batteries, so are the best choices for systems with tight power budgets needing full featured step-down regulators.
