EZ1117CST voltage regulators & voltage controller Series
semtechCompact LDO voltage regulators for stable power supply applications
The EZ1117CST series from Semtech Corporation is a lineup of compact low-dropout (LDO) voltage regulators designed for applications requiring a stable power supply. These regulators are typically used in portable electronics, sensor networks, and battery-powered devices where space is at a premium and noise is a concern.
If you're working on a project that needs a clean, low-noise power rail without the need for external components, the EZ1117CST series is a great choice. They offer a dropout voltage as low as 100 mV, which means they can maintain regulation even when the input voltage is close to the output voltage. This makes them ideal for applications where the input voltage can fluctuate due to battery discharge or other factors.
One thing worth noting is that these regulators come in a tiny package, making them perfect for space-constrained designs. Engineers tend to reach for this when they need a reliable, low-noise voltage regulator that doesn’t take up much board space. Additionally, the series supports a wide range of input voltages, making them versatile for different power supply scenarios. If you're looking to integrate a stable power supply into a design without complicating your PCB layout too much, the EZ1117CST series is definitely worth considering.
