Design a Custom BoardAbout This Component
Three-terminal positive linear voltage regulator delivering fixed 5V output at up to 100mA from input voltages of 7-30V. Features low dropout voltage (1.7V typical), excellent load and line regulation, and integrated thermal protection. Ideal for powering microcontrollers, logic circuits, and analog modules in compact applications requiring space-constrained designs.
Package: SOT-23-3 · 3 pins
Why does this need a breakout?
SOT-23's tiny 0.95mm pin pitch and compact form factor make hand-soldering tedious and prone to bridging errors. A breakout board breaks out the three pins to standard 0.1" spacing for breadboard prototyping, eliminating the need for specialized soldering equipment and enabling fast circuit iteration with transistors, diodes, and small-signal components.
