Design a Custom BoardAbout This Component
Adjustable boost regulator with 1A output current in SOT-23-5 package. Converts lower input voltages to higher regulated outputs with internal 1.5A switch. Suitable for battery-powered applications, LED drivers, and low-power wireless devices requiring compact boost conversion.
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.
