Design a Custom BoardAbout This Component
Linear LED constant current regulator IC designed for automotive applications with preset 10mA output adjustable to 350mA via external resistor. Features low-side control with PWM-capable enable pin (up to 25kHz) for dimming, negative temperature coefficient protection, and integrated design requiring minimal external components. Suitable for LED string driving in automotive interior and decorative lighting.
Package: SOT-23-6 · 6 pins
Why does this need a breakout?
SOT-23-6 packages house precision regulators, voltage references, and level shifters with 0.95mm pin pitch—too fine for hand soldering and incompatible with breadboards. A breakout board provides through-hole headers for prototype work, eliminating soldering difficulty while enabling quick circuit iteration. Essential for developing with compact analog and power management ICs.
