Design a Custom BoardAbout This Component
LED driver and regulator IC in a compact SOT-23-6 surface-mount package capable of delivering up to 1A output current. Integrates linear regulation and LED control functions for single-channel LED dimming and brightness control applications. Suitable for backlighting, indicator LEDs, and low-power LED string driving in space-constrained designs.
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.
