With its wide input range of 3.2V to 34V, the LT1934 can regulate a wide variety of power sources, from 4-cell alkaline batteries and 5V logic rails to unregulated wall transformers and lead-acid batteries. Quiescent current is just 12µA and a zero current shutdown mode disconnects the load from the input source, simplifying power management in battery-powered systems. Burst Mode® operation and the low drop internal power switch result in...
