The TPS6122x family devices provide a power-supply solution for products powered by either a single-cell,two-cell, or three-cell alkaline, NiCd or NiMH, or one-cell Li-lon or Li-polymer battery. Possible output currents depend on the input-to-output voltage ratio. The boost converter is based on a hysteretic controller topology using synchronous rectification to obtain maximum efficiency at minimal quiescent currents. The output voltage of the adjustable version can be programmed by an external resistor divider, or is set internally to a fixed output voltage. The converter can be switched off by a featured enable pin. While being switched off, battery drain is minimized. The device is offered in a 6-pin SC-70 package (DCK) measuring 2 mm X 2 mm to enable small circuit layout size.

Switching regulators, by comparison, offer a significant improvement in conversion efficiency and, consequently, energy savings. Transistors are employed here as well, but instead of being used in a linear variable resistor mode, they are utilized in switched mode as switches that are either in the ON or OFF state.
A voltage regulator is a component of the power supply unit that ensures a steady constant voltage supply through all operational conditions. It regulates voltage during power fluctuations and variations in loads. It can regulate AC as well as DC voltages.
Although it has to be said that voltage regulators usually do control the current, i.e. they have a built-in current-limiting circuit, and they have a thermal shutdown circuit, and thus they don't normally get damaged by a short circuit on the output.
