ST619LB is a boost charge pump DC-DC converter that provides 5V regulated power supply ±4% output at 30mA and overheating. The input voltage range is 2V to 3.6V (two batteries). It requires only 4 external capacitors: two 0.22mF flying input capacitors and 10mF capacitors for the output. Low supply current (200mA typical) makes small, portable and battery-powered devices ideal for powered applications. When the load is turned off the input and supply current is typically 0.02mA. ST619LB is available in SO-8 and DIP-8 packages.
