Description
The NCP1117ST33T3G is a high-performance, low-dropout (LDO) positive voltage regulator capable of delivering an output current in excess of 1.0A. Specifically configured for a fixed 3.3V output, this device is engineered for reliability, maintaining tight regulation even under demanding load conditions. With a maximum dropout voltage of just 950mV at load, it ensures efficient power conversion for a wide range of consumer and industrial electronics.
The NCP1117 series is built with robustness in mind, featuring comprehensive internal protection mechanisms, including output current limiting, safe operating area (SOA) compensation, and thermal shutdown. This ensures the safety of your system even in fault scenarios. Because it requires no minimum load to maintain regulation, it is an exceptionally versatile choice for point-of-regulation applications, battery charging circuits, and as a post-regulator for switching power supplies.
Key Features
- 1A Output Current: Sufficient power for high-demand digital circuits, controllers, and peripheral hardware.
