Design a Custom BoardAbout This Component
Ultra-low dropout linear voltage regulator with 3.3V fixed output and 50mA guaranteed output current. Features 120mV typical dropout at full load, 80µA quiescent current, and TTL-compatible shutdown control. Stable with low-ESR ceramic capacitors, making it ideal for battery-powered and low-noise applications in portable electronics.
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.
