Open-drain output and active-low reset
This lets you connect multiple open-drain reset outputs to the same node — common in multi-rail systems where any one fault should trigger a system reset. The active-low polarity matches the reset input of most MCUs, DSPs, and FPGAs. No level shifting needed if the pull-up voltage matches the logic supply.
The SOT-23-3 package (also known as TO-236-3 or SC-59) is a three-pin surface-mount package. The pinout is standard for this class of supervisor: ground, reset output, and supply input. The small footprint saves board space and fits into dense layouts. Tape & Reel and Cut Tape options are available for both prototyping and production reels.
