The ST619LB is a regulated 5V±4% charge pump DC-DC converter that delivers a stable output current of 30mA over temperature. The converter does not require an inductor, has very low EMI noise, uses small and inexpensive capacitors, and is ideal for small, portable, and battery-powered applications. When shut down, the load is disconnected from the input and the supply current is 0.02μA.
The ST619LB is a step-up charge pump DC-DC converter that delivers a regulated 5 V output with a tolerance of +4%. It operates with an input voltage range of 2 V to 3.6 V and requires only four external capacitors, eliminating the need for inductors. The device is designed for small, portable, and battery-powered applications due to its low operating supply current.
