Reset supervisor for 5V rails
The DS1810-5+TR is a simple reset/power-on reset supervisor monitoring a single 4.62V threshold with an active-low, push-pull output.
TO-92 package and board-fit
Housed in a TO-226-3 / TO-92-3 (TO-226AA) through-hole package with formed leads, the DS1810-5+TR fits the standard 0.100-inch pitch footprint used by 3-pin TO-92 supervisors and linear regulators. The through-hole body suits prototyping, breadboard bring-up, and boards where a rework tech wants to socket the part for easy replacement — the scorch mark tells you which part actually died, and swapping a TO-92 takes thirty seconds with a desoldering iron.
Temperature range and deployment
The 4.62V threshold is set for a nominal 5V rail with a typical tolerance band of ±1.5% to ±2% at the supervisor input; a 5V supply that dips below 4.62V during a brown-out or load transient triggers a clean reset before the logic rails go indeterminate.
For a repair bench stocking a 5V supervisor that sees regular use, this part is a straightforward line-item with no last-time-buy clock ticking.
