KA75330 3.3V Voltage Detector Reset / Enable Controller IC - 10 Pack
Now available from PMD Way is the KA75330 3.3V Voltage Detector Reset / Enable Controller IC in packs of ten.
The KA75330 monitors the voltage on one Input pin, and when that voltage goes below 3.3V, it will pull the Output pin low.
The KA75330 starts running at voltages as low as 0.8V so it'll be the first thing in your circuit that starts up. This little helper can really ease power start-up issues! Works best with microcontrollers and boards that have an Enable pin that is normally pulled high to enable function, and pulled to ground to disable.
This regulator requires at least 2,2uF electrolytic capacitors on both input and output for stability, just make sure your power supply already has those.
