The device can deliver 5V or 3.3V from a two-cell battery input. It features program- mable 5V or 3.3V output via a logic-controlled input, no- load quiescent current of 120 µAandashutdownpinwhich reduces supply current to 10 µA.Theon-chippowerswitch has a low 170mV saturation voltage at a switch current of 1A, a four-fold reduction over prior designs. A 155kHz internal oscillator allows the use of extremely small sur- face mount inductors and capacitors. Operation is guaran- teed at 1.8V input. This allows more energy to be extracted from the battery increasing operating life. The ILIM pin can be used to program peak switch current with a single resistor allowing the use of less expensive and smaller inductors and capacitors in lighter load applications. The LT1300 is available in an 8-lead SOIC package, minimizing board space requirements. For a 5V/12V Selectable Out- put Converter see the LT1301. For increased output cur- rent see the LT1302.
