Design a Custom BoardAbout This Component
The RT9078-33GJ5 is a low-dropout linear regulator providing fixed 3.3V output at up to 300mA from a 1.2V to 5.5V input. It features ultra-low 2µA quiescent current, 0.15V dropout at 300mA, and integrated current-limit and over-temperature protection, making it ideal for battery-powered and portable applications requiring extended runtime.
Package: TSOT-23-5 · 5 pins
Why does this need a breakout?
SOT-23-5 packages are extremely difficult to hand-solder due to 0.95mm pin pitch and tiny leads, making breadboarding impossible. A breakout board breaks out all five pins to standard 0.1" spacing, enabling reliable prototyping without micro-soldering skills or specialized equipment.
