Design a Custom BoardAbout This Component
CMOS low-dropout voltage regulator delivering 300mA at fixed 3.3V output. Features 170mV dropout at full load, 60µVRMS output noise, and 68dB ripple rejection at 1kHz. Low quiescent current (60µA typical) and ultra-low standby current (0.1µA) make it ideal for battery-powered and portable applications including notebooks and datacom equipment.
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.
