Design a Custom BoardAbout This Component
Integrated charge pump voltage regulator in SOT-23-5 surface mount package. Generates negative voltage rails by inverting positive supply voltage using switched capacitor topology. Typical applications include providing negative bias supplies for op-amps, analog circuits, and mixed-signal ICs requiring dual-rail operation from single positive source.
Package: SOT-23-5 · 5 pins
Why does this need a breakout?
This 0.95 mm pitch SMD package is incompatible with breadboards and difficult to hand-solder. A breakout board brings the five pins to standard 0.1″ spacing, enabling rapid prototyping without reflow equipment. Essential for evaluating precision analog ICs like current-sense amplifiers in development circuits.
