Overview
ST619LB SERIES DC-DC CONVERTER REGULATED 5V CHARGE PUMP s s s s s s s 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 DIP-8 SO-8 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.
Low operating supply current (typ 200µA) 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.
02µA.
The ST619LB is available in SO-8 and DIP-8 packages.
