Design a Custom BoardAbout This Component
Automotive-grade low-dropout regulator delivering 300mA at 3.3V with ±1% accuracy. Features high PSRR (75dB @ 1kHz), low output noise (60µVrms), and ultra-low quiescent current (35µA). Wide input range 1.7V–5.25V with integrated enable control. Ideal for noise-sensitive automotive applications including infotainment, RF supplies, and ADAS systems.
Package: SC-74A-5 · 5 pins
Why does this need a breakout?
Tiny 0.95mm pitch SMD makes hand-soldering risky and breadboarding impossible. A breakout board brings these single-gate logic ICs and analog switches to standard 0.1" headers, enabling rapid prototyping and reliable connections without microscopy skills or rework tools.
