This is the DESCRIPTION of ST619LB series: The ST619LB is a step-up charge pump DC-DC converter which delivers a regulated 5V ±4% output at 30mA and over temperature. The input voltage range is 2V to 3.6V (two battery cells). It requires only four external capacitor: two 0.22F flying capacitors, and 10F capacitors at the input and output. Low operating supply current (typ 200A) 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 0.02A. The ST619LB is available in SO-8 and DIP-8 packages.
And these are the features: The first one is regulated 5v ±4% charge pump. The second one is output current guaranteed over temperature of 20ma (vi.2v ),30ma (vi.3v ). The third one is no inductors; very low emi noise. The forth one is uses small, inexpensive capacitors. The fifth one is logic controlled 1a max shut-down supply current. The sixth one is shut down disconnects load from input. The seventh one is available in so-8 and dip-8 packages.
And these are the maximum ratings: Firstly, dc input voltage is from -0.3 to 5.5 v. Secondly, output voltage is from -0.3 to 5.5 v. Thirdly, shutdown input voltage is from -0.3 to (vi + 0.3) v. Fourthly, output current continuous is 120 ma. Fifthly, storage temperature range is from -55 to +150 °c. Sixthly, operating junction temperature range is from -40 to +85 °c.
