DESCRIPTION
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 0.22µF flying capacitors, and 10µF capacitors at the input and output.

■ REGULATED 5V ±4% CHARGE PUMP
■ OUTPUT CURRENT GUARANTEED OVER TEMPERATURE : 20mA (VI ≥ 2V ), 30mA (VI ≥ 3V )
■ NO INDUCTORS; VERY LOW EMI NOISE
■ USES SMALL, INEXPENSIVE CAPACITORS
■ LOGIC CONTROLLED 1µA MAX SHUT-DOWN SUPPLY CURRENT
■ SHUT DOWN DISCONNECTS LOAD FROM INPUT
■ AVAILABLE IN SO-8 AND DIP-8 PACKAGES
