ST619LB DC-DC CONVERTER REGULATED 5V CHARGE PUMP

The ST619LB is a step-up charge pump DC-DC converter which delivers a regulated 5 V ±4 % output at 30 mA and over temperature. The input voltage range is 2 V to 3.6 V (two battery cells).

It requires only four external capacitor: two 0.22 µF flying capacitors, and 10 µF capacitors at the input and output.

Low operating supply current (typ. 200 µA) make the device ideal for small, portable and battery powered applications. When shut down the load is disconnected from the input and the supply current is typically 0.02 µA. The ST619LB is available in SO-8 package
