TOUCHSTONE SEMICONDUCTOR TS3300 boost regulator uses 3.5µA of supply current, and its efficiency performance is constant over a 100:1 span in output current. The boost plus linear regulator operates from supply voltages as low as 0.6V up to 4.5V and can deliver at least 75mA of continuous output current. Unit can be powered from a wide variety of power sources including single or multiple-cell alkaline or single Li-chemistry batteries. The boost regulator’s output voltage range can be user-set from 1.8V to 5.25V to power an entire range of low-power analog circuits, microcontrollers and low-energy Bluetooth™ radios simultaneously.
