Design a Custom BoardAbout This Component
Low-dropout linear voltage regulator delivering 200 mA from 2.5–18 V input with 100 mV typical dropout. Features ±0.5% output accuracy, 60 µA quiescent current, 88 dB PSRR, and logic-controlled shutdown (<1 µA). Includes thermal, current-limit, and SOA protections; compatible with ceramic output capacitors.
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.
