Design a Custom BoardAbout This Component
Ultra-low-noise, low-dropout linear regulator sourcing 1 A with 150 mV dropout and 0.46 μVRMS output noise (10 Hz–100 kHz). Features 110 dB PSRR at 1 kHz, adjustable output 0–5.5 V, and 1.7–5.7 V input range. Includes programmable current limit, power-good output, and soft-start for precision analog and RF applications.
Package: VSON-10-1EP (3×3mm, EP) · 10 pins
Why does this need a breakout?
This 3×3mm VSON package with 0.5mm pitch and hidden pads demands a breakout board for hand assembly—the fine pitch makes soldering impractical without professional equipment, and the no-lead package requires exposed traces or vias for connectivity. Ideal for power management ICs like boost converters, charge controllers, and eFuse switches where breadboarding is impossible. A breakout brings these compact, capable regulators and protection devices into reach for prototype development.
