Design a Custom BoardAbout This Component
Low-dropout linear regulator with 2µA quiescent current, 300mA output capability, and adjustable/fixed voltage options from 0.8V to 5.5V input range. Features enable function, current-limit and over-temperature protection, output discharge, and 75dB PSRR at 1kHz. Ideal for battery-powered and ultra-low-power applications requiring extended runtime.
Package: TSOT-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.
