Design a Custom BoardAbout This Component
Adjustable positive voltage linear LDO regulator delivering up to 300mA with output range 0.8V to 5.5V. Features ultra-low noise (60µVRMS), low dropout voltage (170mV @ 300mA), and high ripple rejection (68dB @ 1kHz). Ideal for battery-powered devices, datacom, and notebook computers requiring clean, regulated power from 2.5V to 6V inputs.
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.
